Question

Find the average rate of change from 1 to 6
Let f(x)=8x-3

Answer 1

Answer:

8

Step-by-step explanation:

To find the average rate of change we use the function

$f(x) = \frac{f(b) - f(a)}{b - a} \\ f(x) = \frac{f(6) - f(1)}{6 - 1} \\ \frac{(8(6) - 3) - (8(1) - 3)}{5} \\ \frac{48 - 3 - (8 - 3)}{5} \\ \frac{45 - 5}{5} \\ \frac{40}{5} \\ 8
