Graph B is the graph that describes the function.
What is a quadratic graph?
A quadratic graph is a graph of quadratic functions which have the power of the variable as 2. They are usually u-curved or inverted v-curved.
Analysis:
if we solve the quadratic function, y = [tex]x^{2}[/tex] -4x -12
when the curve touches the x-axis y = 0
[tex]x^{2}[/tex] -4x -12 = 0
[tex]x^{2}[/tex] -6x +2x -12 = 0
x(x-6) +2(x-6)
(x+2)(x-6) = 0
x = -2 or 6
From the graph, The second graph(graph B) shows the points on the x-axis x = -2 and x = 6.
