Question 1 1. What are the vertical asymptotes of the following function?

Question 2 2. If the domain of the function f(x) = x^2 is 0 ≤ x, what is the range of f?

Question 3 3. Use factoring to find a solution of the following equation: 2x^2+8x = x^2+2x-8. (Remember that if one side of the equation equals zero, and the other side of the equation is a product, then at least one of the parts of the product must equal zero. For example, if 0 = x(3-x), then x must be 0 or (3-x) must be 0.)

Question 4 4. What is the inverse of f(x) = e^x?

Question 5 5. Find x if 4x = 2^4.
