Answer: C. 12

Step-by-step explanation:

      We will substitute -2 for x and solve.

      Given:

F(x) = x² - 2x + 4

      Substitute:

F(-2) = (-2)² - 2(-2) + 4

      Square (-2):

F(-2) = 4 - 2(-2) + 4

      Multiply -2 by -2:

F(-2) = 4 + 4 + 4

      Add:

F(-2) = 12

       C. 12

Answer:

f(-2) = 12

Step-by-step explanation:

Hello!

To evaluate f(x) to -2, we plug in -2 for x in the equation and simplify.

Evaluate f(-2)

  • [tex]f(x) = x^2 - 2x + 4[/tex]
  • [tex]f(-2) = (-2)^2 - 2(-2) + 4[/tex]
  • [tex]f(-2) = 4 + 4 + 4[/tex]
  • [tex]f(-2) = 12[/tex]

The evaluated function is 12.

If this has been graphed, we can simply find f(-2) by looking at the y-values of intersection when x is -2.
