I know it's a long question but the reward is great! Please answer if you truly know how to help!! Thank you!!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.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.Again thank you if you can help me with this!!

Prove that the trajectory of a projectile is parabolic, having the form y = ax + bx2. To obtain this expression, solve the equation x = v0xt for t and substitute it into the expression for y = v0yt − 1 2 gt2. (These equations describe the x and y positions of a projectile that starts at the origin.) You should obtain an equation of the form y = ax + bx2 where a and b are constants.
