Answer:
a) when x approaches negative infinity, A(x) approaches positive infinity and when x approaches infinity, A(x) approaches positive infinity
Step-by-step explanation:
there are 2 ways to figure this out:
1. when you multiply the factors together, you end up with [tex]12x^4-49x^3-86x^{2} -423x-252[/tex]. use the end behavior chart to figure out the end behavior.
look at the [tex]12x^4[/tex]. the exponent is even and the coefficient is positive. therefore, the graph's end behavior goes towards infinity in both directions
2. graph problem and look at the end behavior
