Penjelasan dengan langkah-langkah:

1.

a. (fog)(x) = f(g(x)) = f(5x) = 3(5x)+10 = 15x+10

b. (gof)(x) =g(f(x))= g(3x+10) = 5(3x+10) = 15x + 50

c. (hof)(x) = h(f(x)) = h(3x+10) = 6(3x+10)² - 4

d.(goh)(x)= g(h(x)) = g(6x²-4) = 5(6x²-4) = 30x² - 20

e. ((fog)oh)(x) = (fog)(6x²-4) = 15(6x²-4) +10 = 90x² - 50

f. (fo(goh)(x) = f(30x² - 20) = 3(30x² - 20)+ 10 = 90x² - 50

2.

a. (gof)(x) = 5x-2

4(f(x))+1 = 5x-2

4f(x) = 5x - 2 -1

4f(x) = 5x - 3

f(x) = 5/4x - 3/4

b.

(gof)(x) = x²+2x-7

f(x) + 4 = x²+2x-7

f(x) = x²+2x-7- 4

f(x) = x²+2x-11
