Problem 2 locate and classify the discontinuities of f

Question

Problem 1: If the function f defined by:

Image:

Is continuous everywhere on (-∞,∞), what is the value of f(1)?

1. f(1) = 4

2. f(1) = 5

3. f(1) = 3

4. f(1) = 7

5. f(1) = 6

Problem 2: Locate and classify the discontinuities of f when

f(x) = 2x² - 4x - 16/4 + 3x - x²
