Answer:
x-int: (-1, 0), (-11, 0)
y-int: (0, 11)
Step-by-step explanation:
To find x-int, set equation equal to 0:
x² + 12x + 11
(x + 1)(x + 11)
x = -11, -1
To find y-int, set <em>x</em> = 0
f(0) = 0² + 12(0) = 11
f(0) = 11
Answer:
Step-by-step explanation:
sub equation 1 into 2
2-5x=x²-2x-8
0=x²-2x+5x-8-2
0=x²+3x-10
0=(x-2)(x+5)
x=2 or x=-5
sub x into equation 1
y=2-5(2) or y=2-5(-5)
y=-8 y=27
