Question

The graph represents function 1, and the equation represents function 2: A coordinate plane graph is shown. A horizontal line is graphed passing through the y-axis at y = 6. Function 2 y = 2x + 7 How much more is the rate of change of function 1 than the rate of change of function 2? 1 2 3 4

Answer 1

The answer is "2"

Explanation:

Rate of change of function is given by :

For function y = 6,

rate of change =

because the function is independent of x.

For function y = 2·x + 7,

rate of change =

So, the rate of change of 2 is greater than rate of change of function 1 by 2 - 0 = 2.
