Quadratic Functions: Factored Form Answers

Which point is an x-intercept of the quadratic function f(x) = (x – 4)(x + 2)?(–4, 0)(–2, 0)(0, 2)(4, –2)

The graph of the function f(x) = (x + 6)(x + 2) is shown. Which statements describe the graph? Check all that apply.The vertex is the maximum value.The axis of symmetry is x = –4.The domain is all real numbers.The function is increasing over (–∞, –4). The function is negative over (–6, –2).

The vertex is the [___].

([___],[___])

Which element (A, B, or C) is most likely a metalloid? [___]

What does the underlined word mean in the following sentence?Este traje de baño nuevo es demasiado grande.

Sample Response: The vertex lies on the axis of symmetry, so the axis of symmetry is x = 3. Find any two x-intercepts that are equal distance from the axis of symmetry. Use those x-intercepts to write factors of the function by subtracting their values from x. For example, 2 and 4 are each 1 unit from x = 3, so f(x) = (x – 2)(x – 4) is a possible function.

The function is positive [___].
