Question

7. f(x) = Square root of quantity x plus nine. ; g(x) = 8x - 13 Find f(g(x)). (1 point) f(g(x)) = 2 Square root of quantity two x minus one. f(g(x)) = 8 Square root of quantity x minus four. f(g(x)) = 2 Square root of quantity two x plus one. f(g(x)) = 8 Square root of quantity x plus nine. - 13

Answer 1

f(g(x)) =

`√(8x \: - \: 13) \: + \: 9`

Explanation:

f(x) =

`√(x) \: + \: 9`

g(x) = 8x - 13

f(g(x) =

`√(8x \: - 13) \: + \: 9`
