The graphs below have the same shape. What is the equation of the blue graph?
2 answers:
Answer:
The correct option is C.
Step-by-step explanation:
The given function is
It is given that both graph has same shape it means the equation of blue graph is in the form of
Where, (h,k) is the vertex of the parabola.
From the given graph it is noticed that vertex of blue parabola is (4,1), therefore the eqaution of parabola is
Option C is correct.

It is a cap-size parabola. The parabola "goes down". The graph of this function looks like in this attached picture.
For this question we will use the following relations.
100 centimeters=1 meter (or 1 centimeter= 0.01 meter)
10 millimeter=1 centimeter (or 1 mm=0.1 cm)
60 minutes = 1 hour (or 1 min= hour)
Now, Jackson's speed is 1350 meters per hour. This can be converted to cm per minute as follows:
...Equation 1
Likewise, Jonah's swim speed in cm/min can be calculated as:
...Equation 2
As we can see clearly after comparing Equation 1 and Equation 2, Jonah's swim speed of 7500 cm/min is faster than that of Jackson.
Thus, option B is correct.
