The graph shows a function and its reflection over the X axis. Which equation describes the function? A. y = (x)^2 + 6
B. y = (x - 3)^2
C. y = (x + 3)^2 - 9
D. y = (x + 2)^2 - 25

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

answer: a parabola

steps:

(x-1)(x+4)   = x(x+4) - 1(x+4) = (x^2 + 4x) - (x+4)

                = x^2 +4x -x -4   = x^2 +3x -4

which is a parabola
