![### Mathematical Concepts: True or False Questions
**Instructions:** For each of the questions below, indicate if the statement is true (T) or false (F).
**(a)** Any critical point of a function \( f \) is either a local maximum or local minimum for \( f \).
- \( \circ \) True
- \( \circ \) False
**(b)** Every differentiable function is continuous.
- \( \circ \) True
- \( \circ \) False
**(c)** Any function \( f \) defined on a closed interval \([a, b]\) is guaranteed to have a global maximum, and this maximum must occur either at a critical point of \( f \) in the open interval \((a, b)\) or at one of the endpoints \( a \) or \( b \).
- \( \circ \) True
- \( \circ \) False](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc0c43ed0-a854-4f55-a30b-147647d0ed33%2F791729cd-5d3c-41fa-8a7d-d0a9e87fb4ac%2Faq8w5g_processed.png&w=3840&q=75)

**Determine the interval on which \( f \) is concave up.**
*(Use symbolic notation and fractions where needed. Give your answer as interval in the form \((\ast, \ast)\). Use the symbol \(\infty\) for infinity, \( \cup \) for combining intervals, and an appropriate type of parenthesis "\( (\,, \,) \)", "\( [\,, \,] \)" depending on whether the interval is open or closed. Enter \( \emptyset \) if the interval is empty.)*
