Question

The table represents the function f(x). When f(x) = –3, what is x?

Answer 1

`x=-1`

Explanation:

we know that

Observing the table

For
`x=-1`

The value of the function f(x) is equal to
`f(x)=-3`

therefore

`f(-1)=-3`

That means----> The value of the function f(x) for
`x=-1`

Answer 2

f(x) = x^3 - 2

f(3) = 3^3 - 2 = 27 - 2 = 25
