Question

Please help, Algebra II - Will Fan and Medal.

Answer 1

Compare the functions shown below:

Answer 2

What is the correct order of the functions from least to greatest according to the average rate of change on the interval from x = -1 to x = 3?

Answer 3

the rate of change of that line is a constant
it is the slope
do you know it?

Answer 4

@satellite73 Would 0.5/3 be the slope? I'm pretty bad at this, haha

Answer 5

Sorry, 1.5*/3

Answer 6

You have to find the slope of each function f(x), g(x), and h(x) \[A(x)= \frac{ f(b)-f(a) }{ b-a }\] this is the average rate of change

Answer 7

So what is f(3) for f(x)?

Answer 8

f(3)=((3)+3)^2-2, am I doing okay, so far?

Answer 9

Yup, exactly!

Answer 10

f(3)=(9)^2-2 - > f(3)=81-2 -> 79?

Answer 11

Not quite, 3+3 = 6 :P

Answer 12

Oh whoops... I was thinking of multiplication, for some reason.. f(3)=(6)^2-2 -> f(3)=36-2 - > f(3)=34?

Answer 13

Yup that's good!

Answer 14

now find f(-1)

Answer 15

Yay! ^^

Answer 16
