I. Given the following polynomial:
Check all that apply.
The value of the discriminant is .
There are real roots. , so there are 2 real roots
The parabola is directed upward.
since which is positive number, the parabola directed upward
The axis of symmetry is located at: -> ->the axis of symmetry goes through vertex (,) and it is a vertical line
The graph intersects the y axis at (,).
The graph intersects the x-axis at (, ) and (,) -> -> point (, ) -> -> (,)
II.
Use the quadratic formula to solve the following:
solutions:
