    1st function equation: -x^2 + 8(x-15) simplify: -x^2 +8x-120 2nd equation: -x^2 + 4x+1 Taking derivative will find the highest point of the parabola, since the slope of the parabola at its maximum is 0, and the derivative will allow us to find that. derivative of 1st fuction= -2x + 8 solve for 0 : -2x+8= 0 x= -4 2nd fucntion der. -2x+4 = 0 x= 2 Now that you have those max points, plug them back in and compare which one has the highest maximum of y. so second funcition
