(C) Yes, both conditions for using the intermediate value theorem have been met.

Check Conditions: To use the intermediate value theorem, we need to check two conditions: the function must be continuous on the closed interval $a, b$ , and the value we are looking for (in this case, $0.5$ ) must be between the values of the function at the endpoints of the interval.
Function Continuity: First, let's check if the function $h(x) = \frac{1}{x}$ is continuous on the interval $[-1, 1]$ . We know that the function $\frac{1}{x}$ is not defined at $x = 0$ , which lies within the interval $[-1, 1]$ . Therefore, the function is not continuous on the entire interval.
Use of Theorem: Since the function is not continuous on the interval $[-1, 1]$ due to the discontinuity at $x = 0$ , we cannot use the intermediate value theorem to guarantee that there is a solution to the equation $h(x) = 0.5$ on this interval.
