Which statements are true about the graph of the function f(x) = 6x – 4 + x2? Select two options.

Question

The vertex form of the function is f(x) = (x – 2)2 + 2.
The vertex of the function is (–3, –13).
The axis of symmetry for the function is x = 3.
The graph increases over the interval (–3, infinity).
The function does not cross the x-axis.

Answer 1

The statements that are true about the graph of the function f(x) = 6x – 4 + x2 are:
1. The vertex form of the function is f(x) = (x – 2)2 + 2.
2. The function does not cross the x-axis.
