Which form most quickly reveals the vertex?
1 answer:
Answer:
Step-by-step explanation:
A
A will give you the roots (the x intercepts) just by reading the numbers and doing a small adjustment.
x + 1 = 0
x = - 1 So one of the roots is (-1,0)
x + 5= 0
x = - 5 The other root is (-5,0)
A is not the answer.
B
I have graphed B so that you can see that A is true. See below, Even so, B is in standard form and it is not the answer.
C
The answer is C. The vertex is at 2,27
x - 2 = 0
x = 2
The maximum value is located at 27 which is just read.
That point (2,27) is plotted on the graph.

Answer:
no horizontal asymptote
Step-by-step explanation:
When the degree of the numerator > degree of the denominator there is no horizontal asymptote but there is a slant asymptote.
Dividing the numerator by the denominator gives
= x - 5 +
There is a slant asymptote with equation y = x - 5
