Explain what is meant by the equation lim f(x) = 4.
x→1

A. The values of f(x) can be made as close to 4 as we like by taking x sufficiently close to 1.
B. f(x) = 4 for all values of x.
C. The values of f(x) can be made as close to 1 as we like by taking x sufficiently close to 4.
D. If |x₁ - 1| < x₂ - 1, then |f(x₁) - 4| < |f(x₂) - 4|.
E. If |x₁ - 1| < x₂ - 1, then |f(x₁)-4|≤ |f(x₂)-4|.
