Answer:
f(x) = (x - 2)(x + 2)
Step-by-step explanation:
When you expand out the expression, you should get f(x) = x² - 4, where only vertical movement is present. Therefore, the vertex is on the y-int at (0, -4) and your answer is the 3rd choice.
Answer:
116.15
Step-by-step explanation:
1.95 - 30.00 - 7.20 - 38.50 = 38.50
77.65 = 38.50
x = $116.15
Class B has the most consistant sleep because there is less of a difference between 6.87 and 3.65 than the other classes.
So then n=number of long distance calls, then add the flat rate
long distance cost=number of calls times cost per clll or n times 0.42 or 0.42n
the flat rate is 24
so total is c so
c=24+0.42n
we have

we know that
<u>The Rational Root Theorem</u> states that when a root 'x' is written as a fraction in lowest terms

p is an integer factor of the constant term, and q is an integer factor of the coefficient of the first monomial.
So
in this problem
the constant term is equal to 
and the first monomial is equal to
-----> coefficient is 
So
possible values of p are 
possible values of q are 
therefore
<u>the answer is</u>
The all potential rational roots of f(x) are
(+/-)
,(+/-)
,(+/-)
,(+/-)
