Answer: D
Step-by-step explanation:
No such thing as a vertex of a graph... Eliminate B and C. Try f(3) = 4(3-5)(3+3) is not zero eliminate A. So answer must be D. Check: f(-3) has factor -3+3 = 0. f(5) has factor 5-5 = 0.
Answer:
C. This is the graph of a linear function.
Step-by-step explanation:
Linear function because it's not touching each other.
QUESTION 1
We want to solve,
We factor the denominator of the fraction on the right hand side to get,
This implies
We multiply through by LCM of
We expand to get,
We group like terms and equate everything to zero,
We split the middle term,
We factor to get,
But
is not in the domain of the given equation.
It is an extraneous solution.
is the only solution.
QUESTION 2
We add x to both sides,
We square both sides,
We expand to get,
This implies,
We solve this quadratic equation by factorization,
But
is an extraneous solution
I believe the correct answer would be B. 88 Degrees, because 92 + 88 = 180. Hope this helped!
