Jillian and Josie are trying to find the value of the function, 8x^4-12x^3+3x^2-7x+4 at x=-1. Jillian says the only way to find the answer is to plug in -1. Josie says, no, there is another way. Who is right? Justify your answer.

Josie is correct.

Step-by-step explanation:

There are other ways of finding the value of the function at x = 1.

For example, one way would be graphing or using a graphing device to graph the function. Once graphed, looking for the y-value where x = 1 would also provide the answer.  

0.28277

I got this by plugging in 0.2512 for "A" ( A = π r² ) Then I solved the rest ( divide both sides by pie, then taking the square root from that.
