Question:

In Problem 1-4, plot the function f(x) over interval [1.5, 2.5]. Zoom in on the graph of each function to determine how close x must be to 2 in order that f(x) is within 0.002 of 4. Your answer should be of the form "If x is within ____ of 2, then f(x) is within 0.002 of 4."
1. f(x) = 2x
2. f(x) = x2
3. f(x) = √8x
4. f(x) = 8/x
