And
identify the roots of the quadratic function.
a) x = 0 and x = 4

b) y = 0 and y = 4

c) x = 0 and x = -4

d) y = 0 and y = -4

Step-by-step explanation:

The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.
