Answer:

its B

took the test and got this question right

Using the zeroes concept, it is found that function B could be defined by a cubic equation.

  • The degree of a function depends on the number of zeroes, for example, a first degree function has one zero, a quadratic equation has two, cubic equation has three, and so on...
  • On a graph, the number of zeroes is the number of times the function crosses the x-axis.

In this problem:

  • In Option A, it crosses four times.
  • In Option B, it crosses three times.
  • In Options C and D, it crosses two times.

Hence, option B is a cubic equation.
