Final answer:
The given function f(x) = -10x is a polynomial function of degree 1, with a leading coefficient of -10.
Step-by-step explanation:
The given function f(x) = -10x is a polynomial function. A polynomial function is a function that is defined by a polynomial, which is an algebraic expression consisting of variables and constants combined using addition, subtraction, and multiplication. In this case, the function is a polynomial of degree 1, with a leading coefficient of -10. Therefore, the answer is A) Polynomial of degree 1, leading coefficient -10, linear function.
