Question

find the average rate of change: 2x^2+4

for 3 to 5
for -2 to 0
for -1 to 2

Answer 1

plug in x for all the for X to X, then find the difference between the two, and that's your average rate of change

Answer 2

Here... the average rate of change of a function f(x) from a to b is given by this formula
\[\huge \frac{f(b) - f(a)}{b-a}\]

Answer 3

so... (54-22)/2 = 16 for the first?

Answer 4

Yes. Correct :D
You seem to have gotten the hang of it :)

Answer 5

the rate of change of this fuction is the first derivative which I think is 4x. Good Question! i DON'T KNOW
