Hatshy [7]

Answer

x = 1

Explanation:

Given the following equation

\begin{gathered} (2x+2)^{\frac{1}{2}}=\text{ -2} \\ \text{According to the law of indicies} \\ x^{\frac{1}{2}}\text{ = }\sqrt[]{x} \\ (2x+2)^{\frac{1}{2}}\text{ = }\sqrt[]{(2x\text{ + 2)}} \\ \text{Step 1: Take the square of both sides} \\ \sqrt[]{(2x\text{ + 2) }}\text{ = -2} \\ \sqrt[]{(2x+2)^2}=-2^2 \\ 2x\text{ + 2 = 4} \\ \text{Collect the like terms} \\ 2x\text{ = 4 - 2} \\ 2x\text{ = 2} \\ \text{Divide both sides by 2} \\ \frac{2x}{2}\text{ = }\frac{2}{2} \\ x\text{ = 1} \end{gathered}

Therefore, x = 1

I'm stuck. Help please.

Usually you will see something like g(x) or f(x)

domain means all the x's

so, think of g(4) meaning g(x=4) and g(4 in the domain).

look for 4 on the domain side

you know that f(x) = y

range means all the y's

so its basically saying, look on the domain side for 4 and see what comes out (or =) on the range side.

in this case, it's B) 5
