Consider this formula: G = (A3+B) * 4 - C2

a. Show the order that a single processor would follow to calculate G following the standard order of operations. To do so, break down the equation into the correct order of operations, with one calculation per step. Show the formula for each step, assigning new letters to your calculations as necessary.
b. Find the value of G: if A = 3, B = 4, and C = 5

Function name: poly parameters: int returns: int description: a polynomial of degree n with coefficients a0,a1,a2,a3, . . ,an is the function p(x) = a0+a1x+a2x2+a3 ∗ x3+ . . +an ∗ xn this function can be evaluated at different values of x. for example, if: p(x) = 1+2x+ x2, then p(2) = 1+2 ∗ 2+22 = 9. if p(x) = 1+x2+x4, then p(2) = 21 and p(3) = 91. write a function poly() that takes as input a list of coefficients a0, a1, a2, a3, . . , an of a polynomial p(x) and a value x. the function will return poly(x), which is the value of the polynomial when evaluated at x.
