Question 929788: so i need help on determining the number of the equation y=-2x[squared]+32
i know the formula is -b[squared]-4(a)(c) but in this situation i dont have (a) so would i put 0 or 1 into the equation

You can put this solution on YOUR website!
Maybe you have the equation, y=-2x%5E2%2B32. This is ONE equation. You HAVE one equation.


...i dont have (a) so would i put 0 or 1 into the equation...

Compare that to the form, y=ax%5E2%2Bbx%2Bc.
You have a=-2 and b=0.
