Question

What is the inverse of the function below?

f(x) = 5x - 2

Answer 1

Let's change f(x) to y so the equation is y=5x-2

Answer 2

The inverse is when you switch y and x so that is x=5y-2

Answer 3

Try and solve it should be easier

Answer 4

so would it be f-^1(x)=-2+5x ????

Answer 5

No because when you divide the 5 you divide the whole equation

Answer 6

so it's f^-1=(x-2)/5

Answer 7

SO IS IT f-^1(x)=x+2/5??

Answer 8

ohh srry i did not see u type that

Answer 9

its alright yeah but keep in mind that both x and 2 are being divided by 5
