To construct a polynomial function based on the given zeros and their multiplicities, we need to use the information provided:

  • A zero at \(x = 4\) with multiplicity 1 implies a factor of \((x - 4)^1\).
  • A zero at \(x = -2\) with multiplicity 3 implies a factor of \((x + 2)^3\).

Therefore, the polynomial function can be constructed as follows:

\[ f(x) = (x - 4) (x + 2)^3 \]

Now, let's look at the responses provided:

  1. \( f(x) = (x - 4)(x + 2)^3 \)
  2. \( f(x) = (x + 4)(x - 2) \)
  3. \( f(x) = (x + 4)(x - 2)^3 \)
  4. \( f(x) = (x - 4)(x + 2) \)

The first option matches our derived function.

So, Jaime should write:

\(f(x) = (x - 4)(x + 2)^3\).
