Graph the function f(x) = 3.5(2)x. State the domain and range and give the y-intercept.

• The range of f is the domain of g and the domain of f is...

• The range of f is the domain of g and the domain of f is the range of g. • f(a) = b if and only if g(b) = a. • (a, b) is on the graph of f if and only if (b, a) is on the graph of g. The function f(x) = x3 + 7x + 5 is one-to-one. Since finding a formula for its inverse is beyond the scope of this textbook, use Properties of...

(6) Consider the function f(x, y) = 9 − x^2 − y^2 restricted to the domain x^2/9 + y^2 ≤ 1. This function has a single critical point at (0, 0) (a) Using an appropriate parameterization of the boundary of the domain, find the critical points of f(x, y) restricted to the boundary. (b) Using the method of Lagrange Multipliers, find the critical points of f(x, y) restricted to the boundary. (c) Assuming that the critical points you found were...

Let f be a function with domain the reals and range the reals. Assume that f has a local minimum at each point x in its domain. (This means that, for each x ∈ R, there is an E = Ex > 0 such that, whenever | x−t |< E then f(x) ≤ f(t).) Do not assume that f is differentiable, or continuous, or anything nice like that. Prove that the image of f is countable. (Hint: When I solved...
