The function h is defined as follows. h (x)=x2-9
If the graph of h is translated vertically upward by 4 units, it becomes the graph of a function g.
Find the expression for g(x).

.
?

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
