Y intercept = -12
X-intercept = 6,-2
Explanation:
For the intercepts, you need to understand first what means x-intercept and y-intercept.
X intercept means the point at which the line or the curve that intersects x-axis, and y intercept is the intersection at y-axis.
For the y intercept,
we know at y-axis, x=0
SO,
y =
= -12
So -12 is the y-intercept,
For the x-intercept, we let y=0
(x-6)(x+2) =0
So either Or.
x-6=0 x+2 =0
x=6 x=-2
So 6 and -2 are the x-intercepts.
