Answer:

$300,000.04\ people$

Step-by-step explanation:

we know that

To find how many people live in that city multiply the population density by the area of the city

$(46\ \frac{people}{mi^{2}})(6,521.74\ mi^{2})=300,000.04\ people$

If f(x)=1/x and g(x)=x^2-4x. What two numbers are not in the domain of f o g?

statuscvo [17]

The composed fraction $f \circ g$ means that the input of $f(x)$ is the ouput of $g(x)$ .

So, the chain is

$x \mapsto g(x) \mapsto f(g(x)) = f\circ g = \dfrac{1}{g(x)} = \dfrac{1}{x^2-4x}$

The domain of $f(x)$ is composed by all inputs which are not zero, otherwise we would have a zero denominator.

So, since $f(x)$ doesn't accept 0 as an input, and we want to feed it with $g(x)$ , we conclude that $g(x)$ can't be zero.

So, we have

$f \circ g = f(g(x)) = f(x^2-4x) = \dfrac{1}{x^2-4x} \implies x^2-4x \neq 0$

Since

$x^2-4x = x(x-4)$

we have

$x^2-4x = 0 \iff x(x-4) = 0 \iff x=0 \lor x=4$

Since these two points cases $g(x)$ to vanish, they can't be accepted as inputs by $f(x)$ .
