Use the equation y=-2x^2-2x-1 for the following : a.) identify the intercepts b.) determine the coordinates of the vertex c.) state domain & range
for a: set y to 0 and solve for x to find the x intercepts. then set x to 0 and solve for y to find y intercepts for b: complete the square or use the formula -b/2a for c: quadratics have a domain of element of real numbers and a range that's equal to or less than the y value of your vertex.
still need help?
@dpaInc , yes i do
