Does the parabola with equation x2 – x + 4 = 0 have real or imaginary roots? 1. real, because the discriminant is positive 2. real, because the discriminant is negative 3. imaginary, because the discriminant is positive 4. imaginary, because the discriminant is negative

The parabola with equation has two imaginary roots, because the discriminant is negative.

Step-by-step explanation:

The quadratic formula says that the solutions are

for any quadratic equation like:

The discriminant is the part of the quadratic formula under the square root.

The discriminant can be positive, zero, or negative, and this determines how many solutions there are to the given quadratic equation.

We have the parabola with equation

The discriminant for this equation is , because the discriminant is negative the parabola has two imaginary roots.
