HSA.SSE.B.3 Tutor Intake — Equivalent Forms and Revealed Properties

This short check helps your tutor understand where to start. Answer each question on your own — no notes, but you may use a calculator for the last two sections. If you're not sure, give your best try. The goal is to find what to work on together, not to grade you.

Concepts

A student needs to find the minimum value of
$g(x) = x^2 + 4x - 1$ . Which equivalent form should the
student produce?

Factored form — to read the minimum from the zeros

Vertex form $(x + 2)^2 - 5$ — to read the minimum directly from $k$

Standard form $x^2 + 4x - 1$ — the minimum is the constant $-1$

Vertex form $(x - 2)^2 - 5$ — to read the minimum directly from $k$
