Question

Which represents the inverse of the function f(x) = 4x?h(x) = x + 4Oh(x) = X-4Oh(x) = 2xh(x) =17 1x

Answer 1

f(x) = 4x

To find the inverse of a function, you have to replace every x with an y, as follows:

f(x) = 4y

then, replace f(x) with an x,

x = 4y

and now, isolate y,

x/4 = y

Finally, replace y whit h(x),

h(x) = 1/4x
