Use the given functions to find f (g(x)), and give the restrictions on x.
torisob [31]

Answer:

f(g(x)) = \frac{10x-9}{3 + 3x}

Step-by-step explanation:

Given

f(x) = \frac{1}{x} - 3

g(x) = \frac{3}{x} + 3

Required

Find f(g(x))

If: f(x) = \frac{1}{x} - 3

Then:

f(g(x)) = \frac{1}{3/x + 3} -3

Solve the denominator (take LCM)

f(g(x)) = \frac{1}{\frac{3+3x}{x}} -3

f(g(x)) = \frac{x}{3 + 3x} - 3

It can be solved further as:

f(g(x)) = \frac{x-3(3 + 3x)}{3 + 3x}

f(g(x)) = \frac{x-9 + 9x}{3 + 3x}

f(g(x)) = \frac{10x-9}{3 + 3x}

3/4 = 3/4 * 3/3 = 9/12


Box is 9/12 full after heba ate 1/12 of a box of cereal


Initial fraction will be 9/12+1/12


=10/12= 5/6
