Answer 1

Answer 2

f(x) is same as y so
first replace f(x) with y \[\huge\rm \color{ReD}{y}=4\color{blue}{x}+8\]
to find inverse `switch x and y`
\[\huge\rm \color{blue}{x}=4\color{red}{y}+8\]now solve for y

Answer 3

a. h(x) = 1/4x – 2
b. h(x) = 1/4x + 2
c. h(x) = 1/2x – 2
d. h(x) = 1/2x + 2 @Nnesha

Answer 4

ok. solve the equation for y ^^

Answer 5

Answer 6

:hmm there supposed to be x variable
fist move 8 to the left side (subtract 8 both sides)
and then move 4 to the left side by dividing 4 both sides :=)
