Answer:

D) 26

Step-by-step 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

For this case we have a function of the form [tex]y = f (x).[/tex]

Where:

[tex]f (x) = 3x ^ 2-6x + 2.[/tex]

We must find the value of the function when [tex]x = -2.[/tex]

Substituting we have:

[tex]f (-2) = 3 (-2) ^ 2-6 (-2) +2\\f (-2) = 3 * 4 + 12 + 2\\f (-2) = 12 + 12 + 2\\f (-2) = 26[/tex]

Thus, the value of the function is 26.

26
