Question

The function h is defined as follows.

h(x)=x² +5
If the graph of h is translated vertically upward by 4 units, it becomes the graph of a function f.
Find the expression for f(x).

Answer 1

Explanation:

moving 4 units up means that, when x=0, y has to be 4+5

Therefore,

f(x) =
`x^(2)`+9
