hey, i was just wondering how I would graph these equations step by step. I have a quiz on them tomorrow and I can't figure them out.
1) y = x(squared)(multiplied by)e(to the x)
2) y = (lnx)(squared)
thanks for your help
Great, you have a calculator.
MathMan, I thinkmeans $\displaystyle y=(ln \, x)^2$y = (lnx)(squared)
You need x-intercept, y-intercept, extrema (you might not get all three because some functions do not have some), and a few points. You must know the domain (x-range) so you know what to plot. Ask, or determine yourself.
1. Find those by hand or by a calculator... just plug x into the function. A calculator produces a much better estimate for the points.
2. Plot them.
3. Connect the dots as smoothly as possible.
