Question

How do I find the vertex and all intercepts of the parabola:

f(x)=-x-2x+3

Answer 1

How are you at factoring?

Answer 2

err wait isn't that just f(x) = -3x+3?

Answer 3

I am not sure how to factor in general to find the vertex...

Answer 4

is it supposed to be \[-x^2-2x+3\]

Answer 5

Are you saying the vertex is -x^2-2x+3

Answer 6

The function you entered isn't a parabola.

Answer 7

The entire question indicates> Find the vertex and all intercepts of the parabola. Then sketch and determine window values. The problem is: f(x)=-x^2-2x+3
