Just invert it like:

There you have your common denominator! Don't forget to multiply the numerator as well.
Vertex: (1,-4)
axis of symmetry: x=1
min
minimum value: y=-4
x intercepts: -1, 3
y intercept: -3
i dont know how to find solutions or roots sorry
Answer:

Step-by-step explanation:
If Bella types 50 words in 2 minutes, we can divide 50 by 2 to see how many words she types in 1 minute.

So, Bella types 25 words per minute. When she first began writing her essay, she did not have words to start with, so there is no y-intercept (
).
Therefore, the equation that represents this relation is
.
<u>Solving the equation</u>
We can divide 400 by 25 to determine how many minutes it would take her to finish her essay.

Therefore, it will take her 16 minutes to complete her essay.

There may be a relationship between 'x' and 'y', but we have no equation
that shows what it is. So we don't have the information we need to answer
the question.
