Question

f(x) = Square root of quantity x plus nine.; g(x) = 8x - 13

Find f(g(x)).

f(g(x)) = 2Square root of quantity two x minus one.

f(g(x)) = 8Square root of quantity x minus four.

f(g(x)) = 2Square root of quantity two x plus one.

f(g(x)) = 8Square root of quantity x plus nine. - 13

Answer 1

substitute 8x - 3 for the x in sqrt(+ 9) and simpify

Answer 2
