Answer:

a). f(0) = 7

b). f(\frac{1}{3}) = 6

c). f(-5) = 22

d). x = 9

Step-by-step explanation:

The given function is f(x) = -3x + 7

a). For x = 0

   f(0) = -3(0) + 7

         = 0 + 7

         = 7

b). For x = \frac{1}{3}

    f(\frac{1}{3}) = (-3)(\frac{1}{3})+7

          = -1 + 7

          = 6

c). For x = (-5)

   f(-5) = -3(-5) + 7

          = 15 + 7

          = 22

d). For f(x) = (-20)

    -20 = -3x + 7

     3x = 20 + 7

     3x = 27

       x = 9
