graph of a constant function

  Access full lesson containing this video at: www.yourteacher.com Students learn that direct variation is a relationship between two variables in which the variables have a constant ratio, k, where k is not equal to zero. k is called the constant of variation, and if the variables are x and y, the following formulas can be used to represent direct variation: y/x = k or y = kx. Students also learn that the following formula can be used to represent direct variation between two ordered pairs ...

  In this tutorial I show you what an exponential function is and show you what an exponential graph looks like. I also talk about the constant e and the graph of e^x. This tutorial can be viewed in a larger and clearer form on the ExamSolutions website. To see this goto www.examsolutions.co.uk

Question : If we multiply a constant c to any function, what change will it bring to its graph? For example if we multiply 2 to the graph of f(x) = x^2

Answer : The slope of the tangent at any point will be double (if c = 2), i.e., the graph gets steeper. If c > 1, the graph gets steeper, if 0More from Yahoo Answers
