A family of linear function is given by `f(x)=1+c (x + 3)`, where `c in R`. If a member of this family meets a unit circle centred at origin at two coincident points, then c can be equal to

A family of linear functions is given by f(x)=1+c(x+3) where c in R. If a member of this family meets a unit circle centred at origin in two coincident points then 'c'can be equal to

Statement-1: If limiting points of a family of co-axial system of circles are (1, 1) and (3, 3), then 2x^(2)+2y^(2)-3x-3y=0 is a member of this family passing through the origin. Statement-2: Limiting points of a family of coaxial circles are the centres of the circles with zero radius.
