Question

Given the function f(x) = 4(x+3) - 5, solve for the inverse function when x = 3.

Select one:
a. -21
b. -16
c. -10
d. -1

Answer 1

to find the inverse function rewrite your function...

first using y for f(x). and then switch x and y, that is write x in place of y and y in place of x.

then solve for y. y = the inverse function.

Answer 2

-16

Answer 3

just guessing, eh?

yea what does that mean?

Answer 13

you can put in 3 for f(x) and then solve for x to get the answer you require.

Answer 14

i got 19

Answer 15

? you let f(x) = 3 and then solved for x and got 19? really? I think you put in 3 for x and solved for f(x) (which is NOT what you need to do).

Where are you from?

Answer 16

WAT DOES IT MEAN!!

Answer 17

what does what mean?

Answer 18

ruse

Answer 19

look it up

@chantz417 did you figure it out yet? do you know what to do?

Answer 21

no not really

Answer 22

so instead of f(x), we put 3.

\[\Rightarrow 3=4(x+3)-5\]

now, solve for x (please).

Answer 23

or don't...

Answer 24

i just got back

Answer 25

Answer 26

ok

Answer 27

do i do distributive property for 4(x+3)

Answer 28

you can

Answer 29

oh i found it it was -1
