PLEASE BE QUICK AND ACCURATEAfter 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. 1. 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. 2. 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. 3. 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).

1Select all the correct locations on the tables.Andrew wants to purchase a new television with a screen length that is five times its width. The width of the television screen is 7 inches more than the width of his tablet. Andrew also wants the area of the new television screen to be at least 1,050 square inches.If x is the width of Andrew's tablet, determine which inequality could represent this situation. Then, determine if 8 inches is a reasonable width for his tablet.
