Answer:
First thing I would do would be to plot the y intercept because it the easiest. The y intercept is the c or in your case -3
then I would find the vertex - to do that the formula is -b/2a
in your case that is -1, and that is the x value of your vertex
after that you would plug -1 into the equation
1-2-3=-4
that means that you vertex is (-1, -4)
the x value for your vertex is also known as the line of symmetry
through -1 on the x line, you can draw an imaginary line
lets go back to our y intercept -3, you need to reflect over the line of symmetry
which would be (-2, -3)
after that you need to find your roots, since this equation is easily factorable, I would suggest that method
once you factor it, you should get (x+3)(x-1) =
to find you roots you just need to figure out what the x's are
according to the zero rule of multiplication, you just need what is inside the parenthesis to be zero
so it would be -3 and 1
so that means your roots would be (-3,0) and (1,0)
if u have any questions just comment on this
