A function f: X → Y is defined to be invertible, if there exists a function g : Y → X such that gof = I X and fog = I Y.The function g is called the inverse of f and is denoted by f – 1.Solution: In case we need not find inverse, then we can just show that the functions are one-one & onto. The graph has a vertical asymptote at x=1/3. The.
Consider the graph of the function what is the range of function f

Consider the graph of the derivative function, y = f ′ (x), below: Block content from this web address Determine the following about the original function, f (x): (a) What interval(s) is f (x) increasing/decreasing?.
• A power function f has a rule of the form fx()= xn, where the exponent or power n is a real number. • We will consider graphs of all power functions with integer powers, and some power functions with non-integer powers. • In the next few sections, we will manipulate and combine these building blocks to form a wide variety of functions.Example: Find the domain and range.

Explain how you can use a graph of the function f (x) = 5x - 6 to determine whether its inverse is a function. • The range of f (x) = b x is al l positive real numbers, f (x) > 0 or y > 0. • The graph of f (x) = b x must pass through the point (0, 1) because any number, except zero, raised to the zero power is 1. .

What is the domain of f/x )= 3x 2? all real numbers. In the expression f (x) = 3x - 2, the domain is all real numbers and the graph of the function will be a straight line without discontinuities. The domain of f (x) = 3x - 2 is {x | x is a real number} and this can be denoted as ( - ∞, ∞) for all x ∈ R. A parent function is the simplest function that still satisfies the definition of a certain type of function . For example, when we think of the linear functions which make up a family of functions , the parent function would be y = x..
