To change the shape of a function, you need to stretch or _it.

Step-by-step explanation:

The transformation of functions refers to translation, reflection, compression and stretch. However, translation and reflection only change they position, but not the form. Compression and stretch are the two transformation that actually change the shape of a function, making it bigger or smaller towards one axis.

Therefore, the complete statement would be:

To change the shape of a function, you need to stretch or compress it.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
