Thank you!!! If its not too much trouble, I have been stuck on this question for a while: "Two parables are defined by y = 14x - x^2 and y = 2x^2 - 20x. What is the distance between their maximum and minimum values?" I know I have to rearrange the function and find out if I have to find the min/max value, but I'm lost from there. Sorry if I'm being annoying

Y=-x^2+14x is a downward facing parabola; it will have a maximum value at its vertex so have to find the vertex. The x coordinate of the vertex is at -b/2a= -14/-2=7 . When x=7 y = -(7^2)+14(7)= 49 So vertex is at the point (7,49) Y=2x^2-20x is an upward opening parabola so it will have a minimum value at its vertex. The x coordinate is at -b/2a= 20/4=5. When x=5 y= 2(5^2) -20(5)=-50 So vertex is at (5,-50) Now all you need to do is find the distance (d) between these 2 points which is d^2 = 2^2 +(99^2) d=99.02
