Question

Given the function f(x) = 3(x+2) - 4, solve for the inverse function when x = 2.

Answer 1

first you distribute 3 on (x+2)

Answer 2

then set f(x)=y

Answer 3

so it will be like....?

Answer 4

3x+6 ?

Answer 5

am i right?

Answer 6

oopss.. sorry late response..
you are right, then the function will be like this: \[f(x)=3x+6-4\] simplify it
\[f(x)=3x+2\]
then set f(x)=y\[y=3x+2\]
then switch x and y\[x=3x+2\]
change it in terms of y..

Answer 7

@Eternallyfamous

Answer 8

so then it's y=3x+ 2
?

Answer 9

@Data_LG2

Answer 10

my bad! last equation should be \[x=3y+2\]

Answer 11

so y =3?

Answer 12

nope.. rearrange the equation in terms of y..

Answer 13

no y = 2
