Question

which statements are true about the graph of the function $f(x) = 6x - 4 + x^2$? select two options.

• 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 $(-3, \infty)$.
• the function does not cross the $x$-axis.

Explanation:

Answer:

The vertex of the function is \((-3,-13)\).
The graph increases over the interval \((-3,\infty)\).
