Cannot tell for the given representation

Step-by-step explanation:

Although the function only maps out to 1 y value for every x in the graph, there might be some x values mapping out to two y values beyond the graph, so we cannot tell whether or not it is a function.

Hope this helped.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

x = 23.78
