1: the graph would be similar to y = x^2 except one unit shifted below vertically, it will cut xaxis at x=plus & minus one & so axis of symmetry would be y axis (x= 0), so D
2: C: change x to x- 5 as coz to reach a point in second case you have to put value of x 5 units lesser then before as it's already shifted 5 units in + ve x direction..
