If f(x)=15x+3, then f-1(x)=
Ilya [14]

Answer:

y=x-3/15

Step-by-step explanation:

f(x)=15x+3/y=15x+3

f-1(x) is an inverse function, which means you gotta swap the x an the y:

x=15y+3

The goal is to get y alone, so you minus 3 on both sides to get

x-3=15y

And then divide both sides by 15 to get y alone

x-3/15=y
