Question

11.) Jika f(x) = 2 - x, g(x) = x² + 4x - 5, dan h(x) = 3x - 2, nilai (h o g o f)(3) = ....
A. 26
B. 15 do
C. 0- D.
D. -15
E -26 ​

Answer 1

Verified answer

Nilai (h o g o f)(3) = h(g(f(3))) = h(g(2-3)) = h(g(-1)) = h(x² + 4x - 5) = h(x² + 4(-1) - 5) = h((-1)² + 4(-1) - 5) = h(-6) = 3(-6) - 2 = -16.

Jadi, (h o g o f)(3) = -16, sehingga jawabannya adalah D. -15.
