Question
Consider the following polynomial functions: f(a)=(2a-7+a^2) and g(a)=(5-a)
Which of the following statements about the polynomial functions are true? Select all that apply
The expression that represents the sum of the polynomials is a first-degree polynomial.
The expression that represents the difference of the polynomials illustrates that polynomials are closed under subtraction.
The sum of f(a) and g(a) can be represented by the expression a^2 + a - 2
The difference of f(a) and g(a) can be represented by the expression a^2 + a - 12
The product of f(a) and g(a) can be represented by the expression -a^3 + 3a^2 + 17a - 35
