1

3

4

10

Answer 1

is it c or a

Answer 2

I'd say A, but I'm not completely sure..:/

Answer 3

f(x) = 2x + 2. Solve f-1(x) when x = 4 = 1, A

Answer 4

@e.mccormick

Answer 5

So it's A?

Answer 6

i think a

Answer 7

First, did you find the inverse, and if so what was it?

Answer 8

i got a

Answer 9

Let f(x) = x2 - 81. Find f-1(x).

�square root of the quantity x plus 81

9square root of x

1 over quantity x squared minus 81

x squared over 81i think its d

Answer 10

@LunyMoony

Answer 11

Is d the over one?

Answer 12

B

Answer 13

for which one

Answer 14

And how are you getting that Luny?

Answer 15

wait, what you mean by this"f-1(x)" ?

Answer 16

nevermind I know, sec

Answer 17

\(f(x) = x^2 - 81\). Find \(f^{-1}(x)\) means:

\(x=y^2-81\) solve for y.

Answer 18

my brain is about to exploed

Answer 19

A, I believe

Answer 20

for which question

Answer 21

oh, sry was looking at the wrong one, sec

Answer 22

I think its D to, your last question

Answer 23

Let f(x) = twenty-four over the quantity of 3 x minus two. Find f(-2).

-6

-3

3

6
is it d

Answer 24

@LunyMoony

Answer 25

Let f(x) = x2 - 81. Find f-1(x).

�square root of the quantity x plus 81

9square root of x

1 over quantity x squared minus 81

x squared over 81

Answer 26

is it d

Answer 27

@Popraci

Answer 28

f(x) = 24/(3x-2)
f(x) = 24/(3*(-2) -2)
f(-2) = -3

Answer 29

luny is that ur gf

Answer 30

@LunyMoony is @Popraci ur gf

Answer 31

no, hes a guy and he is a teacher's assiestent

Answer 32

Which function below has the largest slope?


f(x)
x f(x)
-3 -10
-1 -7
1 -4
������g(x)

g(x) equals one-half x plus 3
h(x)

Lance gains 1 level each time he plays his favorite video game. He started at level 10.

f(x)

g(x)

h(x)

The functions all have the same slope

Answer 33

is there a question ?
