The x-intercepts are x=−2 and x=4.
The y-intercept is y=−8.
To find the x-intercepts, set
y to 0 and solve for x:
(x+2)(x−4)=0
This equation will be true if either
x+2=0 or x−4=0.
x+2=0:
x=−2
x−4=0:
x=4
So, the x-intercepts are x=−2 and x=4.
To find the y-intercept, set x to 0 and solve for y:
y=(0+2)(0−4)=2×(−4)=−8
So, the y-intercept is y=−8.
