Question 94414: Need help - just can't get this
Need end behavior
where crosses the x axis
Factors
f(x)= -x^2 + 5x - 6
f(x) = -2x^3 - 2x^2 + 3x - 2
Thank you so much

You can put this solution on YOUR website!
For any function f(x):
Crosses x-axis, x-intercept, is described as any P(x,0)
Plug:
f(x) = 0
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
f(x) = -x^2 + 5x - 6
0 = -x^2 + 5x - 6
0 = (-x + 3)(x - 2)
x = 3 and x = 2

f(x) = -2x^3 - 2x^2 + 3x - 2
Just to make this as simple for me as possible, we are going to use the ol' graphical sense.
x = -2
