$\bf \begin{cases} f(x)=&g(x+1)\\ f(3)=&g(3+1)\\ &g(4)\\[-0.5em] \hrulefill& \hrulefill\\ g(x)=&x^2\\ g(4)=&4^2\\ &16 \end{cases}\qquad \qquad f(3)\implies g(4)\implies 16$

Domain of f of g.

Determine domain of g.

x + 4 ≥ 0

x ≥ -4

Now determine domain of f of g, by first figuring out f of g:

$\frac{x+4}{(x+4)-1}=\frac{x+4}{x+3}$

So x ≠ 3

So our domain is

[-4, -3) ∪ (-3, ∞)

The answer is D.

The manufacturing cost of a cell phone was $136. Sellers first marked up the cost by 25 percent. Sales were poor, so sellers dec

Helen [10]

Manufacturing cost = $136
sellers added 25% = $ 136 * 25/100 = $34
manufacturers cost + 25% = $136 + $34 = $170.
old selling price = $170

Sellers decreased the markup to 17% (of manufacturing cost): $136 x 17/100 = $23.12
New selling price = $136 + $23.12 = $153.12

both of these answers show: original cost + markup value
