Justification with the intermediate value theorem


The table gives selected values of the continuous function f.
Below is Isla's attempt to write a formal justification for the fact that the equation f(x)=200 has a solution where 0x5.
Is Isla's justification complete? If not, why?
Isla's justification:
We are given that f is continuous.
So, according to the intermediate value theorem, f(x)=200 must have a solution when x is between x=0 and x=5.
