Question

Do the following for the given f(x):
graph y=f(x)
identify the vertex and axis of symmetry
evaluate f(-2) and f(3).

f(x)=x^2+x-2
if someone could help me I would greatly appreciate it.

Answer 1

what you need help on?

Answer 2

im not sure how to identify the vertex.
is that when you use -b/2a

Answer 3

yes, the vertex x value for the vertex will be -b/2a

(-1/2,y)

Answer 4

the x value there is also your axis of symmetry of o recall correctly

Answer 5

to find the y values, you need to fill in the x value in the equation :)

Answer 6

the y int would be -2?
