text: maths qn!!! functions and transformations. thanks!!? a.) define f(x)=x^2. express y=x^2-2x in the form f(kx+l)+b . check and investigate the function as a seqiemce of translation and scaling. describe the transformation.   b.) describe the sequence of transformation that will transform this equation x^2-y^2=1 to x^2+2x-4y^2=1. a) let f(kx+l)+b = x^2-2x. then (kx+l)^2+b = x^2-2x. then k^2x^2 + 2klx + l^2+b = x^2-2x. then k^2 = 1, 2kl = -2, and l^2+b = 0. so k = 1 or k = -1. if k = 1, then 2l = -2, so l = -1 and (-1)^2+b = 0 so b=-1. if k = -1, then -2l = -2, so l = 1 and 1^2+b = 0 so b = -1.  so either k = 1, l = -1, and b = -1 or k = -1, l = 1, and b = -1.  b.  i'm not sure how to do that.
