What function is graphed below?

tester [92]

The answer for the exercise shown above is the first option, which is:
<span> f(x)=log(x-3)
The explanation is shown below:
If you substitute the x in the function for values, you will obtain the graph attached above. As you can see on the mentioned graph, when the variable x has the value 4, the value y is 0. Therefore, you have:
</span> f(x)=log(x-3)
  f(x)=log(4-3)
  f(x)=log(1)
  f(x)=0<span>
</span>
