1.Describe how the graph of y = x ^ 2 can be transformed to the graph of the given equation. y = x^2 - 20

2.Describe how to transform the graph of f into the graph of g. f(x) = sqrt(x) and g(x) = sqrt(- x)

3.Describe transformation of the graph of f into the graph of g either a horizontal or vertical stretch f(x) = sqrt(x) and g(x) = sqrt(0.5x)
