Question

If the graph of the function g defined by g(x)=x^2+2 is translated vertically downward by 3 units, it becomes the graph of a function h . Find the expression for h(x) .

h ( x ) = ____

Answer 1

we need only subtract 3 units from g(x)=x^2+2 to obtain the function h(x).
The correct result is h(x)=x^2+2 -1.
