Review carefully how in the Check at bottom of the slide we determined the polynomial p() from the coordinate vector [p]. Use the same procedure to answer the following question: Consider the basis = {3, 2 - 1} of P2. [p] = [7] 2, then
a. p() = 25 - 2
b. p() = 5 - 1
c. p() = 5 - 1
d. p() = 6² - 3
d. p() = 7 + 2
