yessss hold on

This will be plug and chug.  Try several of the X values and see how closely they get the Y, OR, graph all the points and the functions.

acxbox22 · Answer

woah those are some crazy functions...
i would just get a calculator and substitute x into the equation and see if the statement is true...

yeah i figured thats what id have to do.. i feel like that could take a really long time though.

acxbox22 · Answer

That is where a graphing tool can help: https://www.desmos.com/calculator

Here is the start of how that would help with this one: https://www.desmos.com/calculator/45nzq9dvjz Just add the other equations and points. A calculator that graphs can be used similarly, and yes, plugging in points and testing a few can also help.

acxbox22 · Answer

graph the equation and see the points given and see if they are part of the graph
