A. y = x^2 + x - 60
B. y = x^2 + x - 20
C. y = x^2 + 3x - 60
D. y = 3x^2 + x - 60
E. y = 3x^2 + 3x - 60
The parabola is in form of a a^2 + bx +c
The x-intercepts are the solutions to the equation
x1=−b−Squroot(b^2−4ac)/2a
The y-intercept is c, as y intercept means the value of y when x=0. So c = -60?
