Question

f(x) = Square root of quantity x plus eight.; g(x) = 8x - 12
Find f(g(x)).

Answer 1

Here simplify this

f(x) = \[\sqrt{(8x-12) +8}\]

Answer 2

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

f(g(x)) = 8Square root of quantity x plus eight. - 12

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

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

Answer 3

It looks like this...
\[2\sqrt{2x -1}\]

which one would you say describes this one?

Answer 4

3rd one
