Write the prototypes for several function calls, deducing the correct signature from the context in PrototypeTester.cpp Do not implement the functions themselves. That is already done. Place the prototypes in pe04.h. Problem 2 - Write a Function Write a function named quadratic() which computes roots of quadratic equations. Recall that a quadratic equation is one of the form, ax+ bx + c = 0. Your function accepts five arguments: The integer coefficients a, b, and c as three input parameters. Two real number (double) output parameters rooti and root2. Your function should compute the two roots of the quadratic equation and store them into the two output parameters. For example, the equation x2 - 3x - 4 - 0 has roots of x = 4 and x = -1, so the call: double rooti, root2; quadratic(1, -3, -4, rooti, root2); should set root1 to 4.0 and root2 to -1.0. You may assume that the function has two real roots. Recall that the quadratic formula is: X= -b+Vb2 - 4ac 2a Constraints: You should not use any built-in functions from the system libraries except for sqrt() from the header. You must program this function by "hand
