Answer:

$3^{-2}=\left ( \frac{1}{3} \right )^2=\frac{1}{9}$

Step-by-step explanation:

According to the Exponents Law. Whenever we have some number whose exponent is a negative one:

$b^{-2}=\left ( \frac{1}{b} \right )^{2}=\frac{1}{b^{2}}$

The outcome is its reciprocal raised to its positive power.

How can you tell from the equation of a rational function if the function has a hole in the graph ( a removable discontinuity) a

Eva8 [605]

Consider that,

x^2+4x+4 = (x+2)(x+2)

x^2+7x+10 = (x+2)(x+5)

Dividing those expressions leads to

(x^2+4x+4)/(x^2+7x+10) = (x+2)/(x+5)

The intermediate step that happened is that we have (x+2)(x+2) all over (x+2)(x+5), then we have a pair of (x+2) terms cancel as the diagram indicates (see below). This is where the removable discontinuity happens. Specifically when x = -2. Plugging x = -2 into (x+2)/(x+5) produces an output, but it doesn't do the same for the original ratio of quadratics. So we must remove x = -2 from the domain.
