Question

Work through this with me??
What is the rate of change for f(x) = −2 cos 4x − 3 on the interval from x = 0 to x = ?

Answer 1

Answer 2

you are looking for the average rate of change over what interval?
well if you are really finding the average rate of change of f over the interval x=0 to x=?
then you just evaluate:
\[\frac{f(?)-f(0)}{?-0}\]

Answer 3

so what would you do with the ? @freckles

Answer 4

plug it into f
just like you plug in 0 into the f

Answer 5

how do you plug in a question mark lol

Answer 6

\[f(?)=-2\cos(4?)-3\]
