beginning with the graph of f(x)=x^2 what transformations are needed to form g(x)=1/2(x+4)^2-3
A the graph of g(x) is narrower than f(x) and is shifted to the right 4 units and down 3 units.
B the graph of g(x) is narrower than f(x) and is shifted to the left 4 units and down 3 units.
C the graph of g(x) is wider than f(x) and is shifted to the left 4 units and down 3 units.
D the graph of g(x) is wider than f(x) and is shifted to the right 4 units and down 3 units.​
