Write an equation that relates the . Which graph does not represent y as a function of x? We can also represent functions using graphs by plotting all the ordered pairs of a function on a coordinate axis. This can be summed up using what is called the vertical line test.. If, in this case, y is both 4 and 7.68, then it is not a function. Since the graph does not pass the vertical line test, that is, a vertical line can be drawn that passes through more than one point on the graph, then the graph does not represent a function. So, to find it, you simply set x to zero, leaving the constant in the equation alone. (v) The vertical line cuts the graph at most one point R. The given graph represents a function. If you draw a vertical line and it intersects the graph of the function in two . So it is your defense in because from here to here it debates the cycle. 1.2. B. Now come to question: Graph A: There are only one value of Y for every value of X , So it is a function. It still means the same thing. 3) Both f and g are functions. Which are functions? If we can draw any horizontal line that intersects a graph more than once, then the graph does not represent a function because that y value has more than one input. Beat the graph at exactly one point. Answer: No, the graph does not represents a function. An example of a graph that does not represent a function is the complete bipartite graph , with vertices and edges for every . Solution : Drawing a vertical lines across the graph, we get. 2 AX 10 answer choices . y = 2 x 3 and its graph as we developed the vertical line test.

From the bus graph, it is visible that the girl is your dick. Now, for the first graph, if we take a look, every vertical line is going toe. Let's see the second row oil. Describe how the pattern grows and how many tiles are in Figure 0. x. represents the figure number, and . Step-by-step explanation: The x value of a point where a vertical line intersects a function represents the input for that output y value. Which statement describes the mapping? Cordero1063. So let's think about this table right over here. Does this graph represent a function? Graph C: There are only one value of Y for every value of X , So it is function. Q. Describe the transformation precisely. DEFINITION. D do 6 4 2 -10-8 -6 4 20 2 6 8 10 a. Transform figure F using the rule (x,y) (-x, y-8). Not a Function-It does not pass the vertical line test. D. answer choices . If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. dome7w and 11 more users found this answer helpful. We know that in a function, the set of images have a unique preimage, to find that, we have to draw a line parallel to the y-axis on all the curve and then move that line across the x-axis, if at any place we find that there is more than one point of intersection of the curve for a given value of x, That cannot be a function. The given graph does not represents a function. 400 If the vertical line touches the graph at more than one point, then the graph is not a function. The graph of a relation R is the set of all points (x, y) in a coordinate plane such that x is related to y through the relation R. 1.2.2.. How can you tell if a graph is a function? Hope it helps. The table and graph both represents the same relationship. If we graph the points in the table, we have the following graph, Clearly, this graph indicates the assignment of multiple outputs to the inputs x = 1 and x = 3, and therefore does not represent a function . No, this does not represent a function If the graph represents y as a function of x, state the domain and choose the correct range of the function. C. No, because it is not a straight line. 1. Why values on one side of the graph continues to go straight, whereas the other side of the graph starts to come up a little bit, so eventually all real numbers will be included in the range as well.. 3) Both f and g are functions. No, the given graph does not represent a function with an inverse function because horizontal lines can be drawn that intersect the given graph more than once. The table of values has one input for every output. We graph this by graphing . See the answer Show transcribed image text Expert Answer Answer is 3. graphing.
