Evaluate the function f(x) = 2x2 - 6x + 3 for x = -1.

f(-1) = 11

Step-by-step explanation:

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

Let x = -1

f(-1) = 2(-1)^2 -6(-1) +3

      =2*1 +6 +3

       =2+6+3

     = 11

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
