Question

y=2x^2+5x-3
a)determine the x-intercepts
b)determine the vertex
c)determine the axis of symmetry
d)determine the maximum or minimum value, stating whether it is a maximum or a minimum
e)determine the range


can i get the equations so i can try them myself?

For a and b, there is some solving to do.
For the y intercepts, put x=0 in the equation given and solve for y. For the x intercepts, put y=0 in the equation and solve for x with the quadratic equation.

You will have to do some factoring on the equation to put it in standard form.
