Which program calculates the following equation where error checking must be included in the answer? f = X3 + 3x 7Xa +1 VX + a X = input ("Enter X:'); a = input ('Enter a:"); S1 = sqrt(X+a); S2 = 7*X*a + 1; if((51>=0)&&(S2== 0)) f = (x^3 +3*X)/(7*X*a+1) - sqrt(S1); a) fprintf('f = %f ', f); else fprintf('Error'); end a= X = input ('Enter X:"); = input ("Enter a:"); S1 = X+a; S2 = 7*X*a + 1; if((51>=0)&&(52!=0)) f=(x^3 +3*X) 7 (7*X*a+1 - sqrt(S1)); fprintf('f = %f ', f); else fprintf('Error'); end b) X = input ("Enter X:"); a = input ('Enter a:'); S1 = X+a; S2 = 7*X*a + 1; if((S1>=0)&&(S21=0)) f = (x^3 +3*x)/ (7*X*a+1 - sqrt(51)); b) fprintf('f = %f ', f); else fprintf("Error'); end X = input ('Enter X:"); a = input ("Enter a:"); S1 = X+a; S2 = 7*X*a+1; if((S1>=0)&&(S2=0)) f= (x^3 + 3*X)/(7*X*a+1) - sqrt(S1); c) Ofprintf('f = %f ', f); else fprintf('Error'); end X = input ("Enter X:"); a = input ("Enter a:"); S1 = X+a; S2 = 7*X*a+1; if((S1>=0)&&($2>0)) f= (x^3 + 3*x/7*X*a+1) - S1; d) fprintf('f= %f ', f); else fprintf("Error'); end
