Best ResponseYou've already chosen the best response.0Create a table of values for a linear function. A drone is in the distance, flying upward in a straight line. It intersects the rainbow at two points. Choose the points where your drone intersects the parabola and create a table of at least four values for the function. Remember to include the two points of intersection in your table.

Best ResponseYou've already chosen the best response.03)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 yintercepts of the rainbow? Explain what each intercept represents. Is the linear function you created positive or negative? Explain. What are the solutions or solution to the system of equations created? Explain what it or they represent.

Best ResponseYou've already chosen the best response.0any two points where gridlines meet. Or if you have a graphing calculator you can pick points with integers or simple fractions

Best ResponseYou've already chosen the best response.0The line has to intersect the parabola twice AND move upward. You need a lower point on the left side and a higher point on the right side dw:1433865603177:dw

Best ResponseYou've already chosen the best response.0You chose 5 on the right, but that won't really work with moving upward. Try 5 on the left, and plug it into the equation we found above to find the ycoordinate.

Best ResponseYou've already chosen the best response.0that was for the question with the table. The equation for the line is y = 9x + 56 and you have two points on it. Find any two other random points dw:1433867320239:dw

Best ResponseYou've already chosen the best response.0the domain of the rainbow is [6,6] and the range is [0,36] and it's just the shape of the rainbow. The linear function is increasing and positive and represents the path of the drone. the solutions are (5,11 and (4,20) and they are where the drone passes through the rainbow
