Increasing and Decreasing Functions The more you know about the graph of a function, the more you know about the function itself. Consider the graph shown in Figure 1.37. Moving from left to right, this graph falls from to is constant from to and rises from to x 2 x 4. x 2 x 0, x 0 x 2, Section 1.4 Graphs of Functions 117
Example Draw the graphs of the functions: f(x) = 2; g(x) = 2x+ 1: Graphing functions As you progress through calculus, your ability to picture the graph of a function will increase using sophisticated tools such as limits and derivatives. The most basic method of getting a picture of the graph of a function is to use the join-the-dots method.
THE GRAPH OF A FUNCTION The graph of a function is the set of all ordered pairs (x, y) where y is the output for the input value x. If x and y are real numbers, then we can represent the graph of a function as points in the coordinate plane. The vertical line test provides a way to determine if a set in the coordinate plane is the graph of a ...
2. Plotting the graph of a function If we have a function given by a formula, we can try to plot its graph. Suppose, for example, that we have a function f defined by f(x) = 3x2 −4. The argument of the function (the independent variable) is x, and the output (the dependent variable) is 3x2 − 4. So we can calculate the output of the ...

Very important in sketching the graph is finding the Critical points by dividing the period by 4. This gives you the interval between “special” happenings on the graph. Notes 2 y =cos(x+30! 30!

Chapter II: Functions and Graphs Prof. D. R. Patil Chapter II : Functions and Graphs 2.1: Notation and Operations Definition: A function is defined as a relation that “maps” one element from the input set into an element from the output set.
Functions and their Graphs Functions A function from a set D to a set Y is a rule that assigns a unique (single) element ( T)∈𝑌 P K ℎ T∈𝐷 The set D of all possible input values is called the domain of the function. The set of all values of ƒ(x) as x varies throughout D is called the range of the function.
Graphing Functions: The graph of a function f often reveals its behavior more clearly than tabular or algebraic representations, thus familiarity with the graphs of selected basic functions is an important precursor to studying calculus. The graph of f is just the set of points {(x,y) : x ∈ domain,y = f(x)}. It

1.1 Functions and Their Graphs 6 Definition. The graph of an even function is said to be symmetric about the y-axis. The graph of an odd function is said to be symmetric about the origin. Example. Exercise 1.1.58. Definition. A linear function is a function of the form f(x) = mx + b, where m and b are constants.
