okay basically f(x) = x^2 -31 is the same thing as y = x^2 - 31. So if the value of x is like 10 then it will be f(10) = 10^2 - 31

Also for a chart for the x and y values you basically plug x value in x^2 - 31 and what ever you get is the y value. For example if you put 1 in for the x value you will get -30 for the y value
