F(x) = V2x<br> g(x) = V18x<br> Find (f .g)(x). Assume x2 0.

Nina [5.8K]

Answer:

fog(x) is D = 6 $\sqrt{x}$

Step-by-step explanation:

I. square all value, so f(x) is 2x then g(x) is 18x

II. Replace x.value in f(x) with g(x).value = 2(18x)

III. If x is 1, 2(18*1) will be 36; find root, so answer is 6

If x is 2, 2(18*2) will be 72; find root, so answer is 6 $\sqrt{2}$

Hope it help, sorry if I'm done it wrong, but I think it's gonna be the right answer. :)
