Question

Let f(x) = 3x2 - 6x + 2. Find f(-2).

A) 20

B) 22

C) 24

D) 26

Answer 1

For this case we have a function of the form
`y = f (x).`

Where:

`f (x) = 3x ^ 2-6x + 2.`

We must find the value of the function when
`x = -2.`

Substituting we have:

`f (-2) = 3 (-2) ^ 2-6 (-2) +2\\f (-2) = 3 * 4 + 12 + 2\\f (-2) = 12 + 12 + 2\\f (-2) = 26`

Thus, the value of the function is 26.

Answer:

26

Option D

Answer 2

D) 26

Explanation:

f(x) = 3x^2 - 6x + 2

Let x = -2

f(-2) = 3(-2)^2 - 6(-2) + 2

=3(4) +12+2

= 12 +12+2

=26
