Question

Help with quadratic functions?

Answer 1

Can someone tell me how to find the average rate of change for f(x) from x = 4 to x = 7?
Here's the equation: \[f(x) = 2(x − 11)2 + 4 \]

Answer 2

\[f(x) = 2(x -11)2 + 4 \]

Answer 3

\(\sf \Large avg. rate= \frac{f(7)-f(4)}{7-4}\)

Answer 4

F(4) = -84 and F(7) = 48...idk where to go from there

Answer 5

@data_LG2 So the average rate is 3?

Answer 6

Can you explain how you did this?

Answer 7
