Can somebody help me with these 2 problems. i need examples.
1. compare the function g(x) = Ix+cI, where c is any real number, with the function f(x) = IxI. Describe the axis of symmetry, the domain and the range of g.
2. compare the function h(x) = x + d, where d is any real number, with the function f(x) = IxI. Describe the axis of symmetry, the domain and the range of g.

the I___I is the absolute value
