Examine what happens around and at the critical value for x.

Change in sign occurs around 2x-1=0. This means for x at



You must understand that x is still allowed to take the value ; but that the sign changes for before and after . Also, do not confuse f(x) with .

Stronger than just "assume". You could and should be able to support your choice, and actually, ...... YES.

D: The graph is "V-shaped."
Absolute-value graphs are v-shaped, and so domain are all REALS

Substituting (- 2, 5) into the equation will make it TRUE

Therefore, it's obvious that  is FALSE.
