Question

If ƒ (x ) = 3x2 - x, find ƒ (-2).

Answer 1

f(-2) is 14.

Explanation:

We have been given the function:

We have to find f(-2)

That means put x= -2 in the given function we get:

After simplification we will get:

After further simplification we will get the required result:

Hence, ƒ (-2) is 14
