And so if we wanted to write it out, we could say f is continuous, is continuous, but, but zero is not between, between f of four and f of six. So the intermediate value theorem does not apply. All right, let's do the second one. So here they say, can we use the intermediate value theorem to say that there is a value c such that f of c equals zero and two is less than or equal to c is less than or equal to four? If so, write a justification. So we are given that f is continuous. So let me write that down.
