Question

ok can I have forgotten how to find inverse of a function can someone refresh my memory
If the function f (x) over R → R is defined by f (x) = x^3 + 3, find f −1(x).

Answer 1

well I don't know what R==>R mean's... but\[y=x^3+3\]\[x=y^3+3\]\[x-3=y^3\]\[y=\sqrt[3]{x-3}\]

Answer 2

@purplec16 now i remember it just converting y into x thanks

Answer 3

and then solve for y

Answer 4

You're welcome!
