tolong ya kak jawabnya pakai cara

no. 1
a) f(x) = 2 - 4x
b) f(-2) = 2 - 4(-2) = 2 + 8 = 10
    f(0) = 2 - 4(0) = 2 - 0 = 2
    f(2) = 2 - 4(2) = 2 - 8 = - 6
    f(4) = 2 - 4(4) = 2 - 16 = -14

no. 2
a) g(x) = 5x - 8
b) g(-2) = 5(-2) - 8 = -10 - 8 = -18
c) g(a) = 17
    5a - 8 = 17
    5a = 25
      a = 5
