WebWhen a cubic polynomial function has one real root and two complex roots, a simple method allows us to visually locate the complex roots. We will begin with a cubic, x)g, (with a real root at r and two complex roots, where the real part of the complex roots is not equal to r. Technique: Construct a tangent from the real root . r, (0) to . g (x WebA parabola is a U-shaped curve that is drawn for a quadratic function, f (x) = ax2 + bx + c. The graph of the parabola is downward (or opens down), when the value of a is less than 0, a < 0. The graph of parabola is upward (or opens up) when the value of a is more than 0, a > 0. Hence, the direction of parabola is determined by sign of ...

WebYou will see the formula involves the square root of b² - 4ac We call b² - 4ac the Discriminant If the discriminant is negative, then its square root is not real, so the equation has imaginary (or non-real) roots. If the discriminant is non-negative, the roots are real. Simple as that! Philip Lloyd put a tick in the boxWebThe graph of this quadratic function shows that there are no real roots (zeros) because the graph does not cross the x-axis. Such a graph tells us that the roots of the equation are complex numbers, and will appear in the form a ± bi.
