You can only graph a system of linear equations.
Replace f(x) with y
swtich x and y
solve for y
replace y with f⁻¹(x)
f(x)=4x+8
y=4x+8
x=4y+8
x-8=4y
1/4x-2=y
y=1/4x-2
f⁻¹(x)=1/4x-2
none of the above
Answer: what do you mean by this
Step-by-step explanation:
the answer about be am number one child so yeah
To solve
if you have |a|=b, solve a=b and a=-b
|4x+12|=16
solve
4x+12=16 and 4x+12=-16
minus 12 both sides
4x=4 and 4x=-28
divide both sides by 4
x=1 and x=-7
