Pretty please, purchase the one on the right.
If you ever find yourself at home without a graphing calculator, there are some spectacular free options online. Check out Desmos or Geogebra. Even with these wonderful options out there for us to use, we still need a graphing calculator to take standardized tests (here's looking at you SAT *uncomfortably long pause*). Those tests do not allow the use of calculator programs on computers or phones or iPod/iPad-type devices. The money you spend on a good calculator is well worth not having to get a tutor AND the increased score on the tests .
