Learn how to tell if a function is increasing or decreasing. See examples of both positive linear graphs and negative linear graphs and practice...
What is an example of a linear function equation? A linear function equation is any equation that will create a straight line. This includes f(x)=4x+2, and f(x)=6x - 4 and f(x)=-71x + 5. What is the formula for a linear function? The most basic formula for a a linear funct...
Every function in the Cartesian plane stems from a particular parent function. Parent functions: square function For example, every linear function can be generated from the parent function f(x) = x; Every other possible linear function of the form y = mx + b is a child function of this...
What is plotting graphs? Plotting graphs allows us to accurately plot coordinates onto a grid to produce the graph of a function. We can plot a variety of different graphs. Linear functions which produce straight-line graphs but we can also plot other polynomials such as quadratic functions or...

When we draw the graphs of these linear equations they produce two straight lines. These two lines intersect at (1,5). So the solution to the simultaneous equations is x = 3 and y = 2.Example 2: Solving simultaneous equations by elimination (subtraction) Solve: \[\begin{array}{l} 6 ...

The TREND function in Excel is a statistical function that computes the linear trend line based on the given linear data set. It calculates the predictive values of Y for given array values of X and uses the least square method based on the given two data series. The TREND function in Exc...
Theshape of the graphof a first degree polynomial is a straight line (although note that the line can’t be horizontal or vertical). Thelinear functionf(x) = mx + bis an example of a first degree polynomial. The graph of the polynomial function y =3x+2 is a straight line. ...
In order to find the derivative of the parent function y=f(x)=x2, which is a parabola, apply the rule stated above to define the derivative dydx to be f′(x)=2x. This first derivative then creates a linear function. An example of a parent function and its derivativeLesson...
