Use the Intermediate Value Theorem (1VT) to show that the function. f(x) = lex² - 11x-7 has a zero in the interval [-1,2]. Find the value of c guaranteed by the theorem.

Let f(x)=4(3)x−1. Evaluate f(3)

Let f(x) = = √9 - x + 5. Determine f-¹(x) and the the domain of f¹(x). ƒ-¹(x) Domain of f-¹(x) = = (Write the domain using interval notation.)

Let f(x) = 3csc(4x).  Find the domain and range of f(x)
