Graph the function f(x)=3x.Question:Graph the function f(x)=3x. Exponential Function:An exponential function is one of the common types of functions one may encounter in mathematics. In an exponential function, the independent variable x in a function f(x) is at the exponent. The base of...
For example, if the exponential function is y = 3x, the y-intercept is (0,1). If y = abx, a > 0 0 < b < 1, the exponential graph has the following properties: The graph is decreasing Domain and range The domain is all real numbers or (-∞, ∞)...

a)f(x)=3−xb)f(x)=3x+1c)f(x)=3xd)f(x)=3x−2 Exponential Functions: Exponential functions are functions that rapidly increase or decrease (depending on the exponent term). The "exponential" term in the name refers to the location of the independ...
The article discusses an effective way of teaching the graph of exponential function and its inverse graph. Topics covered include the need for allowing students to sketch their own graph as well as identify...
Graph the given functions on a common screen. How are these graphs related? y=3x,y=10x,y=(13)x,y=(110)x Exponential Functions: An exponential function is formed by taking a number to an exponent that contains our variable. The most basic exponential...
