Question

If f(x) = x³ - 2, find f(3).

Answer 1

25

Explanation:

`f(x)=x^3-2 \\\\f(3)=(3)^3-2= \\\\27-2= \\\\25`

Hope this helps!

Answer 2

Answer: 25

Explanation: Notice that f is a function of x. So we want to find f(3).

We find f(3) by plugging 3 in for x everywhere

that x appears in the function.

So we have (3)³ - 2.

(3)³ is equal to 3 × 3 × 3 or 27.

So we have 27 - 2 which is 25.

So f(3) is equal to 25.
