Question

If f(x) = x2 + 1 and g(x) = x - 4, which value is equivalent to (fºg)(10)?

Answer 1

2x - 3..... 2*10 - 3 = 17

Explanation:

Fog) = g(fx)) = f(x) - 4 => 2x - 3

Answer 2

37

Explanation:

Substitute x = 10 into g(x), then substitute the result into f(x)

g(10) = 10 - 4 = 6 then

f(6) = 6^2 + 1 = 36 + 1 = 37
