Suppose y = - x^2 - 8 x - 13
Find the following information for this function.
The coordinates of the Vertex are ( -4 , 3 ).
This parabola has 2 x-intercepts.
This parabola attains a Maximum value of 3 .
These intercepts occur at:
x = ?
(8 +or- (64-4(-1)(-13))**(1/2)) / 2(-1)
x = -4 + (3^(1/2))
x = -4 - (3^(1/2))
something is admist?
