Answer:
[tex]x < 2[/tex], [tex]x > 6[/tex]
Step-by-step explanation:
We are identifying the x-values for which the graph of y = f(x) is less than 0. This is when the curve is below the x-axis, or when the y-values are negative.
We can identify these values as:
[tex]x < 2[/tex], [tex]x > 6[/tex]
A sign chart for this function clearly demonstrates this:
[tex]\text{ }\ \ \ - \ \,\stackrel{0}{} \,+\, \stackrel{0}{} \, \ -\\ \leftarrow \!\!- \!\!- \!\! - \! |\!\! -\!\! -\!\! - \! \!\! |\!\! -\!\! -\!\! -\! \!\rightarrow \\ \text{ }\ \ \ \ \ \ \ \,2\ \ \ \ \,6[/tex]
