Question

For the graphed function f(x) = (4)x − 1 + 2, calculate the average rate of change from x = 1 to x = 2.

Answer 1

rate of change = \[\frac{ f(x_{1}) - f(x_{2}) }{ x_{1} - x_{2} }\]

Answer 2

thank you for replying so fast. :)

so i just plug in the numbers.

Answer 3

Yeah, direct substitution.

Answer 4

how do i know what x 1 and 2 are? is it just the x=1 and x=2 from the equation

Answer 5

You have the freedom to let x_{1} = 1 or 2
I prefer letting x_{1} = 2 , x_{2} = 1
