Assume that: Degree 3 Polynomial: is defined by four numbers as the coefficients of a degree-3 polynomial of the form: P3(x)=a3x3+a2x2+a1x+a0 Degree 4 Polynomial: is defined by five numbers as the coefficients of a degree- 4 polynomial of the form: P4(x)=a4x4+a3x3+a2x2+a1x+a0 The following provides the details of the functions to be implemented: void write_polynomial3(double a0, double a1, double a2, double a3): Writes the polynomial in a pretty format. No sign replications should be allowed. For example: write_polynomial3(-1.0,1.0,-3.2,0.0); should print: x3+x23.2x void write_polynomial4(double a0, double a1, double a2, double a3, double a4): Writes the polynomial in a pretty format like write_polynomial3
