1.) F(x) = x²-8x-8 maka f(1) adalah... 2.) F(x) = 32x + 43 G(x) = 4x + 5 maka F(-3) adalah... Tolong bantuin jawab yaa:(

1). f(x) = x^2 -8x - 8
f(1) = (1)^2 -8(1) -8
f(1) = 1 - 8 - 8 = -15 2). f(x) = 32x + 43 g(x) = 4x + 5 f(-3) = [f(g(x))] g(x) = -3 4x + 5 = -3 4x = -8 x = -2 Maka f(-2) = 32.(-2) + 43 = -21

1 f(1)= 1^2-8*1-8
= 1-8-8
= - 15
2. (fog)(x) = f (g(x)
= 32(4x+5)+43
= 128x+160+43
= 128x+203
f(-3)= 128 (-3) + 203
= -384 + 203
= 181
semoga jawaban saya membantu....terimakasih
