Explanation:

A polynomial function is an expression consisting of variables (like \( x \)) and coefficients, combined using addition, subtraction, and multiplication, with non - negative integer exponents on the variables. In the function \( f(x)=9x^{3}-8.3x + 10 \), the exponents of \( x \) are \( 3 \), \( 1 \) (for the term \( - 8.3x\), since \( x=x^{1}\)) and \( 0 \) (for the constant term \( 10 = 10x^{0}\)), all of which are non - negative integers. Also, the operations used are addition, subtraction, and multiplication of the variable \( x \) with coefficients. So, this function meets the definition of a polynomial function.

Answer:

True
