a). Find the specified function values for the following polynomials:

We're just plugging in values of \(t.\)

(a): \(9(-3)^3+8(-3)^2-4(-3)-9=-168.\)

So, just plug the values of \(t\), listed in your question, like how I solved it!

Rick, it appears as if tertre's slight typo has caused an askew answer. 

The original function was defined as \(Q(t)=9t^3+8t^2-4t-9\). Unfortunately, terte evaluated the function as \(Q(t)=9t^{\textcolor{red}{2}}+8t^2-4t-9\). What a tragic error!

Continue evaluating the function at \(Q(-1)\text{ and }Q(-b)\), and you will be done quite soon. 

**OOPS, I know you have told me to call you Rick in future posts.**
