HELP! Determine for each x-value whether it is in the domain of f or not.

-2: in domain

0: in domain

3: not in domain

Step-by-step explanation:

First, understand that the numerator cannot be 0:

(for example, can you find 0/7? How about 0/3?)

Therefore, the x-value that makes the numerator equal to zero makes the function unsolvable:

x-3=0

x=3

So, 3 cannot be in domain.

The denominator can be 0, so -2 can be in domain.

0 does not make the numerator to 0, so zero can be in domain.

I hope this helps :)

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
