Question

Find the rate of change of the function h(x) = 4x – 3 on the interval 0 ≤ x ≤ 1. The rate of change is .

Answer 1

slope = (1 -(-3)) / (1-0) = 4/1 = 4

Explanation:

the function is linear, so the rate of change is constant. Another word for rate of change is slope. The slope of the line is 4.

y = mx + b (m is the slope; b is the y-intercept)We can do the math if your teacher wants.

f(x) = 4x -3

f(1) = 4 -3 = 1

f(0) = 0 -3 = -3

slope = (1 -(-3)) / (1-0) = 4/1 = 4

hope this helped :) <3
