Find (f•f) (0)<br> F(x)=3x-2
NNADVOKAT [17]

Answer:  (f·f)(0) = 4

              (fof)(0) = -8

<u>Step-by-step explanation:</u>

f(x) = 3x - 2

(f·f)(x) = (3x - 2)(3x - 2)

         = 9x² - 12x + 4

(f·f)(0) = 9(0)² - 12(0) + 4

          = 4

(fof) = 3(3x - 2) - 2

       = 9x - 8

(fof)(0) = 9(0) - 8

           = -8
