Unformatted text preview: f ( x ) = x 2 + √ x +2. What is its domain? Write the range of f-1 ( x ) in interval notation. Compute the value f-1 (4). Which of these numbers is NOT in the domain of the function f-1 and why? , 1 , 2 , 4 , 5 Note: if you have trouble making a decision about ”5” that is all right. You could consult a graph of f ( x ), use an equation solver, or use intermediate value theorem, which we will discuss in Lecture 8; the idea is to make you think about it after ﬁguring out the other four using algebra or by trying some simple guesses. .. 3. Solve the following logarithmic equation: log( x + 4)-log(1 + √ x ) = 1 2 log( x ) . Now solve the equation: log(4-x )-log(1-√ x ) = 1 2 log( x ) ....
