5. (5) The modeling content standards for high school are to:

   1. (a) model situations in context with polynomial, exponential, logarithmic, and trigonometric functions. This standard should incorporate cultural context relating to Montana Indigenous Peoples and local communities by:

      1. (i) determining if a set of data is best modeled by a polynomial, exponential, logarithmic, or trigonometric function or none, and explaining why; and
      2. (ii) understanding that there are contexts where solutions may not lie on the curve;
