Question

math problem

Answer 1

well, based off the previous answers, its got to be negative 1

Answer 2

lol im not sure

Answer 3

not sure? az explained to you the same thing several times bro

Answer 4

"(x, y) on the normal function

for the inverse function, it would be (y, x)"

Answer 5

@darkknight

Answer 6

another way to write that would be

for your function f(x)

if f(\(\color{orange}{x}\)) = \(\color{red}{a}\)

then for your inverse function \( f^{-1}(x)\)

then
\( f^{-1}(\color{red}{a}) = \color{orange}{x}\)

the x-value of the inverse function is going to be the y-value of the normal function

which means that the y-value of the inverse function is going to be the x-value of the normal function

Answer 7

im not sure

Answer 8

im not getting it sorry

Answer 9

we're looking for \( f^{-1}(1)\)

1 is the x value of the INVERSE function

so that means 1 should be the y-value of the normal function

so the y-value to the inverse function is going to be the x-value to the normal function

so go find what the x-value is when y is 1 on your normal function

Answer 10

-1

Answer 13

okay, one step at a time?

We're looking for \( f^{-1}(1)\)

right?

Answer 14

\( f^{-1} (\color{red}{1})\)

that 1 is the X-VALUE of the INVERSE function

and we want to find out the Y-VALUE of the INVERSE function

Answer 15

and remember if we have

(a, b) of our normal function
the INVERSE function is going to be flipped and will be (b, a)

so that means

1 is the X-VALUE of the INVERSE function
and the Y-VALUE of the normal function

Answer 16

so to find the Y-VALUE of the INVERSE function

we need to find the X-VALUE of the normal function
and we know that the normal function has a y-value of 1

so look at your graph, what is the x-value when y is 1?

Answer 17

-4

Answer 18

so the X-VALUE of the NORMAL function

is going to be the Y-VALUE of our INVERSE function

and so that's your answer

Answer 19

the ansers -4?

Answer 20

yes

remember we were trying to find the y-value for the inverse function

we know that the x-value of the inverse function is the same as the y-value of the normal function

so we found the x-value that gives us the y-value on the normal function

and that x-value would be the y-value of the inverse function

(x,y) inverse is (y, x)
