Answer:</h3>
c. Both A and B

Step-by-step explanation:</h3>
A function is a mapping that maps each element of its domain (student's name) to exactly one element of its co-domain (favorite ...). Assuming student names are unique and the notion of "favorite" is exclusive (can't have two or more "favorites" of the same type), then both A and B describe mappings that are functions.
Expression: f(x) = [x - 4] / [x^2 + 13x + 36].
The vertical asympotes is f(a) when the denominator of f(x) is zero and at least one side limit when you approach to a is infinite or negative infinite.
The we have to factor the polynomial in the denominator to identify the roots and the limit of the function when x approachs to the roots.
x^2 + 13x + 36 = (x + 9)(x +4) => roots are x = -9 and x = -4
Now you can write the expresion as: f(x) = [x - 4] / [ (x +4)(x+9) ]
Find the limits when x approachs to each root.
Limit of f(x) when x approachs to - 4 by the right is negative infinite and limit when x approach - 4 by the left is infinite, then x = - 4 is a vertical asymptote.
Limit of f(x) when x approachs to - 9 by the left is negative infinite and limit when x approach - 9 by the right is infinite, then x = - 9 is a vertical asymptote.
Answer: x = -9 and x = -4 are the two asymptotes.

Step-by-step explanation:
(8x - 7)(
The x^2 term has to come out to 8x^2.
The 8 is already there.
So your first term in the second factor is x.
(8x - 7) ( x
Now the question is what is the sign after the x. Since the question shows +7 the only way that can happen is if both signs in the factors are the same.
Since (8x - 7) has been given to you and you need 7 to come out plus, then the sign after x must minus. Both signs must be the same.
(8x - 7)(x -
Last, what comes after the minus sign? You already have a minus 7 so you need something to multiply by 7 to get seven.
That should be a one.
(8x - 7)(x - 1)
x - 1 is you answer. I leave you to check the middle term. It is - 15
