Functions are basically another way of expressing a way to get y or x or anything (mostly used for graphs) You will see functions like f(x)= 23y-5 (that was made up). Basically the number in the parenthesis in front of the f is what you're finding. So the equation after the equal sign is how to find whatever is being found. So in this case, finding x can be pretty easy. By the way, when graphing this you have x as the run and y as the rise.

I need help with all the questions:)

The radical parts are gonna be easiest. You plug the radicals into your calculator and get a decimal. Next, you determine which decimal is greater. For turning fractions into decimals, change the fractions into improper fractions and divide the numerator by the denominator (the top number and the bottom number). You'll get a fraction then compare.

For the graphing area, you do the same thing, turn everything into decimals and place them on the graph.

Good luck!
