Introduction for types of functions graphs:
Function graphs f is the collection of all ordered pairs (x, f(x)). In particular, and the real number is x, a graph means the graphical representation of this collection , in the form of a curve on a Cartesian plane, together with Cartesian axes, etc.Curve sketching is Graphing on the Cartesian plane.An ordered pair (x₁, x₂) of real numbers can be an function input x , the graph is the collection of all ordered triples (x₁, x₂, f(x₁, x₂)), and its graphical representation is a surface .

Types of Functions Graphs for Exponential:

For any number a ≠ 1,a>0, the function f : R → R defined by f(x) = ax is called an exponential function.
Note: R+ (the set of all positive real numbers) for exponential function the range
Examples of this types:
Draw the graphs of exponential functions examples f : R → R+ defined by (1) f(x) = 2^x (2) f(x)=3^x (3) f(x)=10^x
Solution:
For all these function f(x) = 1 when x = 0. Thus they cut the y axis at y = 1. For any real value of x, they never become zero. Hence the related curves to the above function do not meet the x-axis for real x. (or meet the x-axis at − ∞) Fig
