12. A second-degree polynomial in x is given by the expression ax 2 + bx + c, where a, b, and c are known numbers and a is not equal to zero. Write a C++ function named polyTwo(a,b.c,x) that computes and returns the value of a second-degree polynomial for any passed values of a, b, c, and x. 13. A. Write a function named totamt() that accepts four actual integer arguments named quarters, dimes, nickels, and pennies, which represent the number of quarters, dimes, nickels, and pennies in a piggy bank. The function should determine the dollar value of the number of quarters, dimes, nickels, and pennies passed to it and display the calculated value
