1) y = x^2 - 11x + 18
-
1) Set y equal to 0:
0=x^2-11x+18
Now foil the equation:
0 = (x-9) * (x-2)
Set each part of that equation equal to 0:
x-9 = 0
x=9
AND
x-2=0
x=2
The zeros of the function are x = 9 and x = 2
0=x^2-11x+18
Now foil the equation:
0 = (x-9) * (x-2)
Set each part of that equation equal to 0:
x-9 = 0
x=9
AND
x-2=0
x=2
The zeros of the function are x = 9 and x = 2
