If the quadratic function is written as ax2 + bx + c, then it has no x-intercepts if the discriminant, (b2 - 4ac), is negative.

Why does the discriminant determine the number and type of the solutions for a quadratic equation?

A quadratic equation is wholly defined by its coefficients. The solutions or roots of the quadratic can, therefore, be determined by a function of these coefficients - and this function called the quadratic formula. Within this function, there is one part that specifically determines the number and types of solutions it is therefore called the discriminant: it discriminates between the different types of solutions.

How can a quadratic function have both a maximum and a minimum point?

A quadratic function can only have either a maximum or a minimum point, not both. The shape of the graph, which is a parabola, determines this: if the parabola opens upwards (the coefficient of the (x^2) term is positive), it has a minimum point; if it opens downwards (the coefficient is negative), it has a maximum point. Therefore, a quadratic function cannot exhibit both extreme values simultaneously.

Is a square root function the inverse function of a quadratic function?

Yes, the square root function is considered the inverse of a quadratic function, but only when the quadratic function is restricted to a specific domain. For example, the function ( f(x) = x^2 ) is a quadratic function, and its inverse, ( f^{-1}(x) = \sqrt{x} ), applies when ( x ) is non-negative (i.e., restricting the domain of the quadratic to ( x \geq 0 )). Without this restriction, the inverse would not be a function since a single output from the quadratic can correspond to two inputs.
