Question

Jawab no 4 dan 6 saja mohon bantuan nya

Answer 1

5. gof(x) = 3 - x
f(x) + 2 = 3 - x
f(x) = 3 - 2 - x
f(5) = 1 - 5 = - 4
fog(p) = 1 + (3 - p)
4 - p = 1
p = 3
6. gof(x) = 4x² + 5x - 1
g(2x + 7) = 4x² + 5x - 1
2x + 7 = p maka x = (p-7)/2
g(p) = 4(p-7 /2)² + 5(p-7)2 - 1
= p² - 14p + 49 + 5/2p - 35/2 - 1 dikali 2
2p² - 28p + 98 + 5p - 35 - 2
2p² - 23p + 61
