D--because it has y^2 in the equation and to isolate y you have to take the square root, the graph is going to be curved rather than linear.

Answer:
The rate of change is of 2.25 degrees per hour.
Step-by-step explanation:
The rate of change in degrees per hour is given by by the change in temperature divided by the change in time(by number of hours).
In this question:
From 6 am to 2 pm, there are 12 - 6 + 2 - 0 = 6 + 2 = 8 hours
The change in temperature was of 76 - 58 = 18º
Rate of change:
18º/8 = 2.25º
The rate of change is of 2.25 degrees per hour.
Whoa just a second there.
What is the question ?
Is the question "Find the percent of increase ?"
In that case, the answer is 300% .
Here's why:
The amount of increase is 75.
The amount of increase as a fraction of
the original amount is
75 / 25 = 3.00 .
To change any number to a percent,
move the decimal point 2 places that way ===> .
3.00 = 300% .
______________________________
The question could have been different.
It could have been "What is the amount of the increase ?"
That's 75.
It could have been "How many times larger is 100 than 25 ?"
100 is 4 times as large as 25, and 3 times larger.
It could have been "How many times has 25 been increased ?"
This is a terrible question ... there are a lot of those in schools.
The answer could be "25 was only increased once, by 75."
The answer could be "25 was increased to 4 times its size."
The answer could be "25 was increased by 3 times its size."
