For any function f(x) =y = f(x) + C ,c<0 the graph shifts down by c units.
For the function y = Cf(x) If C > 1 stretches it in the y-direction .We can stretch or compress it in the x-direction by multiplying x by a constant.
The given function f(x)=\(3x^{2}.\)is stretched in y direction by 3 units and shifted down by 4 units to have the graph g(x)=\(9x^{2}. -4.\)
