Question

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

Answer 1

Answer:

f(-2) is 14.

Step-by-step 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, $f(-2)\text{is}14$

Answer 2

3f-2-f would probaly be your answer
