Question

Two functions are shown at the top.

which statement describes the rates of change of the two functions? ​

a: The rate of change is 2 for both function a and function b.

b: the rate of change is 3 for both function a and function b

c: the rate of change is greater for function b than for function a​

Answer 1

C

Explanation:

Rate of change is the slope

Function A:

Slope = change in y/Change in x

= (9-3)/(3-0) = 6/3 = 2

Function B:

Clearly the slope is 3

(y = mx + c, m is the slope)

Rate of change of B is more than A
