PLEASE HELP ME, I DON'T UNDERSTAND THIS! :(

Mathematics
1 answer:
allsm [11]3 years ago

Answer Choice 1

Take it step by step!

First find what sqrt(x-7) is like. Compare it to sqrt(x).

You can see that in sqrt(x), when x = 0, y = 0. However, in sqrt(x-7), when x = 7, y = 0. When y = 0, sqrt(x-7) is <em>7 more</em>, which means it is shifted <em>7 units</em> to the right.

Similarly, +8 means that whatever sqrt(x-7) is, you add 8 more <em>to y</em>. Adding on extra for <em>y</em> is just moving it up by <em>8</em> units.

Hope that helped,
