Question

Given the function, f(x) = 2x^2 - x + 1, calculate the average rate of change of the function from x = 1 to x = 3. I need help!

Answer 1

@fran345
So I am assuming the change in y

Answer 2

@fran345
in which you would first plug x in

2(1)^2 - 1 + 1 = 4
2(3)^2 - 3 + 1 = 34

Answer 3

changes from 1 to 3 = 30
30/2 = 15

Answer 4

Is your answer 15? I don't have that for my choices.
