We learned about a few different “modifiers” of functions. You can translate or dilate functions in various different ways.

1. Translation

The two marked numbers are translations that move the origin of the function. The one attached to the X value is a translation on the X axis. This one is reversed, so x-7 actually increases the X value of the origin by 7. The one attached to the Y value is a translation on the Y axis. This one is normal, so + 5 increases the Y value of the origin by 5.

2. Dilation

The marked number is the factor of dilation. The higher the factor, the more the Y value changes per increase in the X value. This “stretches” the function upwards.
