# Translations of Graphs $y=f(x)+b$ and $y=f(x-a)$

## Translation Rule 1

For $y=f(x)+b$, the effect of $b$ is to translate the graph vertically through $b$ units.
• If $b \gt 0$, it moves upwards.
• If $b \lt 0$, it moves downwards.

## Translation Rule 2

For $y=f(x-a)$, the effect of $a$ is to translate the graph horizontally through $a$ units.
• If $a \gt 0$, it moves right.
• If $a \lt 0$, it moves left.

## Translation Rule 3

For $y=f(x-a)+b$, the graph is translated horizontally $a$ units and vertically $b$ units.

### Example 1

Given $(x)=x^2$ is translated to $g(x)=(x-3)^2+2$, find the image of the point $(0,0)$ on $f(x)$.

### Example 2

Given $(x)=x^2$ is translated to $g(x)=(x-3)^2+2$, find the point of $f(x)$ which correspond to the point $(1,6)$ on $g(x)$.
