Quadratic Function

A business analyst uses the function $f(x) = 5x^2 - 12x + 100$ to model a company's projected revenue over $x$ months. Given that the output values of this function are determined by a polynomial expression, how should this function be classified?

A business analyst uses the function $f(x) = x^2 + 10x + 100$ to model the projected growth of a startup company. True or False: This model is correctly classified as a polynomial function because its range values are defined by a polynomial expression.

A quality control engineer uses the function $T(x) = x^2 + 5x + 6$ to monitor the thickness of a steel plate during production. Because the range values of this function are defined by a polynomial expression, the relationship $T(x)$ is formally categorized as a(n) ____ function.
