Answer: Choice B

Step-by-step explanation:

At first glance, it doesn't appear that choice B is quadratic. But we can rearrange things like so


(y)/(x-1) = x\\\\y = x(x-1)\\\\y = x^2-x\\\\

This is quadratic because the largest exponent here is "2".

It fits the template
y = ax^2+bx+c where a = 1, b = -1, c = 0.

Extra info:

  • Choices A and D are linear since they can be rearranged into the format of
    y = mx+b (aka slope-intercept form).
  • Choice C is an exponential function. This is due to the fact the variable x is in the exponent.
  • If you're ever stuck, then graphing is a good way to go. Desmos and GeoGebra are two graphing tools I recommend. Choices A and D can be ruled out since they graph out straight lines. Choice C is ruled out because it's an exponential curve that goes up forever. Quadratic curves are parabolic bowl shapes.
