Final answer:
To determine if a function is in vertex or standard form, one must examine the function's equation. Vertex form is written as f(x) = a(x-h)^2 + k, while the standard form is f(x) = ax^2 + bx + c. In the absence of the function's equation, it cannot be determined which form the function is in.
Step-by-step explanation:
To determine whether a function is in vertex form or standard form, you need to look at the structure of the function's equation. The vertex form of a quadratic function is typically written as f(x) = a(x-h)^2 + k, where (h, k) is the vertex of the parabola. On the other hand, the standard form of a quadratic function is written as f(x) = ax^2 + bx + c, where a, b, and c are constants, and the highest degree term is ax^2.
Without the actual function provided, it is impossible to determine if the function is in vertex or standard form. More information would be needed to answer this question accurately. In the context of this particular question, the answer would be option 3) Cannot be determined due to the lack of a provided function.
