Question

Which graph shows the solution set of 00" id="TexFormula1" title="\frac{x-1}{x-3} \ \textless \ 0" alt="\frac{x-1}{x-3} \ \textless \ 0" align="absmiddle" class="latex-formula">?

Answer 1

Answer:

Step-by-step explanation:

f(x) = (x - 1)/(x - 3) < 0

The critical points are x = 1 and x = 3

When x < 1, f(x) > 0

When 1 < x < 3,  f(x) < 0  

When x > 3,   f(x) > 0

Note  when x = 3 f(x) has no value and when x = 1 f(x) = 0.

I can't see all the graphs very well  but there should be a red line between 1 and 3 with a clear circle on x = 1 and x = 3.

Looks like its the last choice.
