Answer:

c

Step-by-step explanation:

First off, we know that (g ° f)(2) is just both functions done in a ordered fashion. In this case, f(x) is done first.

To figure out what f(2) is, all we have to do is find where x = 2 is on the graph. In this case it is on point (2, 3). The input is the x and the output is the y, so f(2) = 3.

Then, we can figure out what g(3) by locating x = 3 on line g. It shows the point (3, 0). This means that g(3) = 0.

If n^-2 = 1/16, then n could be which of the following?
Zepler [3.9K]

Answer:

The correct choice is

\boxed{n=4}

Step-by-step explanation:

The given equation is

n^{-2}=\frac{1}{16}

We rewrite the left hand side of the equation as a power(a number to a given exponent.

n^{-2}=\frac{1}{4^2}

Recall that;

\frac{1}{a^m}=a^{-m}

We apply this property to obtain;

n^{-2}=4^{-2}

Since the exponents are the same, the bases are also the same.

Therefore n=4
