Question

The function g is defined as follows.

g(x)=x² +1
If the graph of g is translated vertically upward by 4 units, it becomes the graph of a function h.
Find the expression for h (x).

Answer 1

h(x) = g(x) + 5 = x² + 5

Explanation:

Since the graph is translated vertically upward by 4 units, there is no change in the x values; for the same x value the new y value is +4 times the old y value
