Question

The default variable in case of solve(‘f(x,y,p,a,l)’) command is __________

(a) x

(b) Variables near to x

(c) Variables away from x

(d) No default variable

Answer 1

Right option is (a) x

The best I can explain: Unless specified, the solve command would take x as the default variable who’s solution is being sought. If the function did not have x as an independent parameter, the default variable would’ve been variables near to x.
