Solution Summary: The author explains that the function f(t) is neither continuous nor piecewise continuous on any interval.
B. The graph of f(x) is given by
(-14)
(1,4)
(-1,–2)
(5,-2)
(3, -4)
(4, 5)
Determine is f is continuous at x = c.
(a) x = -4
(c) x = 1
(e) x = 5
(b) x = -1
(d) z 3
4. Let function ƒ: R → R and function g: R → R be two functions for which f(g(x)) = x and g(f(x)) = x. Through some combination of pictures
and/or words, explain the following: if f(a) is equal to b and ƒ' (a) is equal to m (where m is nonzero), then it follows that g′ (b) is equal to
1. If f(x) is a function such that f(1) = 2, f(n + 1) = (3f(n)+1)/3 for n = 1, 2, 3, ...,
what is the value of f(100)?
