Answer 1

it's given f(x) =a tan bx
in the plot we are given a point (pi/12,-2)
i.e at x=pi/12 f(x)=-2
since we are getting y=-2 at x=pi/12 that means the solution of tan bx will be either +1 or -1
i.e b(pi/12)=npi/4
b=3n
since the graph looks similar to graph of -tanx
means a is negative and tanbx is positive
so b*pi/12=pi/4
or b=3
y=a*tan3x
at x=pi/12 y =-2
so a=-2
b=3
