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.1. The expression that represents the sum of the polynomials is a first-degree polynomial2. the expression that represents thedifference of the polynomials illustrates that polynomials are closed under subtration3. the sun off (a) and g (a) can be represented by the expression of a^2 + a-124. The product of f(a) and g(a) can be represented by the expression -a^3 + 3a^2 + 17A - 35

Answer 1

The given polynomials are:

`\begin{gathered} f(a)=a^2+2a-7 \\ g(a)=5-a \end{gathered}`

The sum of the polynomials f(a) + g(a) is given by:
