You know that 1/2 an hour is equal to 30 minutes, and 3/4 of an hour is equal to 45 minutes.
Using this you can then solve for how many pages she read per minute by dividing the number of pages read by the number of minutes read:11 pages/ 30 minutes to give you Monday's reading speed,and18 pages/ 45 minutes to give you Tuesday's reading speed.
Next, to calculate a percentage increase you need to do the following:
1. Determine the difference between the speeds (this means you will subtract Monday's reading speed from Tuesday's reading speed.)
2. Next you take that number and divide it by Monday's reading speed.
3. Multiply that answer by 100 to get the percentage.
I'm not going to tell you the speeds, as you should try to attempt to solve it by yourself, and I'm sure you need to show your work. I will however tell you that you should find there was a 3.3% increase from Monday to Tuesday.
If you need more help, let me know!

Remember that the vertex form of a parabola is
where
is the vertex of the parabola.
Now, to find the vertex of the parabola, we are going to use the vertex formula:
For a quadratic of the form
, the vertex
is given by:
We know form our quadratic that
and
, so let's use our formula to find
:
Now we can evaluate our function at
to find
:
Now, we can rewrite our parabola in vertex form:
We can conclude that the correct answer is: y = 6(x + 1)2 – 16
