Question

Pls help, thx u!
If ƒ (x ) = 3x 2 - x, find ƒ (-2). 10 14 38

Answer 1

f(-2) is 14.

Explanation:

We have been given the function:

`f(x)=3x^2-x`

We have to find f(-2)

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

`3(-2)^2-(-2)`

After simplification we will get:

`12+2`

After further simplification we will get the required result:

`14`

Hence,
`f(-2)\text{is}14`
