F(x) = x² + 2x – 4g(x) = x² – 4x – 6 (g o f) (1) ?​

Penyelesaian

f(x) = x² + 2x – 4

g(x) = x² – 4x – 6

~

(gof)(1)

g(f(1))

g((1)² + 2(1) – 4)

g(1 + 2 – 4)

g(3 – 4)

g(-1)

(-1)² – 4(-1) – 6

1 + 4 – 6

5 – 6

-1

Penyelesaian:

f(x)=x²+2x-4

g(x)=x²-4x-6

(g o f)(1)=g(f(1))

. =g((1)²+2(1)-4)

. =g(1+2-4)

. =g(3-4)

. =g(-1)

. =(-1)²-4(-1)-6

. =1+4-6

. =-1
