ANSWER
The vertex of the graph of

is

EXPLANATION
The vertex form of a parabola is given by

where

is the vertex of the parabola.
The function given to us is

This is already in the vertex form.
When we compare this to the general vertex form, we have,


and

Therefore the vertex of the parabola is

Hence the correct answer is option A.
Answer:

Step-by-step explanation:
Given

Determine the quotient
See attachment for complete process.
First, divide 125x^3 by 5x

Write
at the top
Multiply
by 

Subtract from 125x^3 - 8
i.e.

Step 2:
Divide 50x^2 by 5x

Write
at the top
Multiply
by 

Subtract from 50x^2 - 8
i.e.

Step 3:
Divide 20x by 5x

Write
at the top
Multiply
by 

Subtract from 20x - 8
i.e.

Hence:

Answer:
-7/18
Step-by-step explanation:
To multiply fractions, you just multiply the top number by the top number and the bottom number by the bottom number. Also, you have to watch the sign.
In this case, we have a positive fraction multiplied by a negative fraction, meaning that our answer must be negative.
So we have- 2x7 / 4x9.
This is simplified to be- 14/36, or 7/18.
However, the answer is actually -7/18, since the number must be negative.
Let me know if this helps.
