How do you find an exponential function given two points? Exponential Function The exponential function has the form {eq}y=ab^{x} {/eq}, where {eq}b {/eq} is the base which must be greater than zero and other than {eq}1 {/eq}. {eq}x {/eq} is the independent variable. To ob...
For example, we will take our exponential function from above, f(x) = bx, and use it to find table values for f(x) = 3x. Step One: Create a table for x and f(x) x f(x) Step Two: Choose values for x. x f(x) -2 -1 0 1 2 Step Three: Evaluate the function fo...

How to find the horizontal intercept of a logarithmic function? Find a logarithmic function given two points: (2,1) and (8,3) . What are Logarithmic Functions? What is their relationship with exponential functions? Find a logarithmic equation that relates y and x. Explain. x 1 2 3 4 5...
The exponential function exhas the property that its derivative is equal to the function itself. Therefore: d/dx ex= ex Finding the derivative of other powers of e can than be done by using the chain rule. For example e2x^2is a function of the form f(g(x)) where f(x) = exand ...
Solving for limits of linear functions approaching values other than infinity. Example problem: Find the limit of y = 2x + 2 as x tends to 0. The limit for this function is 0 at x = 0, and ∞ for x=∞ Step 1: Set up an equation for the problem:Use the usual form for a lim...
Finding the difference quotient for a functionf(x) is simply a matter of findingf(x+h) and plugging bothf(x) andf(x+h) into the difference quotient formula, then simplifying. This all may be old news to you; however, what you may not be familiar with is how to find the difference...
