Key Point. A function of the form f(x) = ax (where a > 0) is called an exponential function. The function f(x) = 1x is just the constant function f(x) = 1. The function f(x) = ax for a > 1 has a graph which is close to the x-axis for negative x and increases rapidly for positive x.

Prove the function f: R ? R defined by f ( x) = 3 x + 2 is one-to-one. Assume f ( x 1) = f ( x 2), which means 3 x 1 + 2 = 3 x 2 + 2. so x 1 = x 2.
PDF/X was the first ISO standard based on PDF technology. A subset of the PDF specification, PDF/X was designed to enable PDF files to meet specific user needs. For example, the relevant files must be complete, i.e., self-sufficient.
