After a dreary day of rain, the sun peeks through the clouds and a rainbow forms. You notice the rainbow is the shape of a parabola.
The equation for this parabola is y = -x2 + 36.

In the distance, an airplane is taking off. As it ascends during take-off, it makes a slanted line that cuts through the rainbow at two points. Create a table of at least four values for the function that includes two points of intersection between the airplane and the rainbow.
Analyze the two functions. Answer the following reflection questions in complete sentences.
What is the domain and range of the rainbow? Explain what the domain and range represent. Do all of the values make sense in this situation? Why or why not?
What are the x- and y-intercepts of the rainbow? Explain what each intercept represents.
Is the linear function you created with your table positive or negative? Explain.
What are the solutions or solution to the system of equations created? Explain what it or they represent.
Create your own piecewise function with at least two functions. Explain, using complete sentences, the steps for graphing the function. Graph the function by hand or using a graphing software of your choice (remember to submit the graph).

is this math or english geez

Answer: Hope this helps


Step-by-step explanation:

The solution and the problem is as follows:

Y= -(-2)^2+36

Y= -4+36

Y=32

Y= -(1)^2+36

y= -1+36

y = 35

The points will be (-2, 32), (1,35)

I will use slope intercept

Formula is f(x) = mx+b

M is y^2-y^1 / x^2-x^1

B will be one of the points, such as 32 or 35

35 = b + 1

Minus the 1 from both sides

B = 34

So f(x) will be f(x) = x + 34

1. Analyze the two functions. Answer the following reflection questions in complete sentences.

o What is the domain and range of the rainbow? Explain what the domain and range represent. Do all of the values make sense in this situation? Why or why not?

The domain is in the x axis.  The range is in the y axis.  The values y make sense.

o What are the x- and y-intercepts of the rainbow? Explain what each intercept represents.

The x- and y- intercepts of the rainbow are from the equation.  

o Is the linear function you created with your table positive or negative? Explain.

The graph opens downward which makes the linear function negative. However, the I made the function positive since the airplane is moving up.

o What are the solutions or solution to the system of equations created? Explain what it or they represent.

The solution to the system of equation represents the y and x intercept for the slope intercept. It will also, show where the airplane will be the rainbow.  The two points are (-5, 11) (-4, 20)


• How can graphing be applied to solving systems of nonlinear equations?

This can be applied to finding points that intersect.  

• How can constraints be used to model a real-world situation?

Real world situations can happen when a pilot is look out of the cockpit and notices a rainbow and when he will be able to tell the passenger’s to look out.  Also when he would need to get from point A to B.
