Answer: x-intercept(s): (2,0),(−1,0)(2,0),(-1,0)
x-intercept(s): (2,0),(−1,0)(2,0),(-1,0)y-intercept(s): (0,−2)
Explanation:
To find the x-intercept(s), substitute in 0 for y and solve for x.
0=x2−x−2
Solve the equation.
Rewrite the equation as x2−x−2
Factor x2−x−2 using the AC method.
(x−2)(x+1)=0
Set x−2 equal to 0 and solve for x.
x=2
Set x+1x+1 equal to 00 and solve for xx.
x=−1
The solution is the result of x−2=0x-2=0 and x+1=0
x=2,−1
