What is the rate of change for the function f (x) = 2x-3

2

Step-by-step explanation:

f (x) = 2x - 3 is a linear function

The rate of change of a linear function is the measure of the slope.

The equation is in slope - intercept form, that is

y = mx + c (m is the slope and c the y - intercept)

y = 2x - 3 has slope m = 2

Thus rate of change = 2
