Linear functions are used to model situations that show a constant rate of change between 2 variables. For example, the relation between feet and inches is always 12 inches/foot. so a linear function would be y = 12 x where y is the number of inches and x is the number of feet. y = 24 x models the number of hours in any given number of days {x}. Business applications abound. If a cell phone company charges a start-up fee of $50 and then $.05 for every minute used, the function is y = .05 x + 50.
The labour cost of calling out a workman = fixed [call out] cost plus an hourly rate.
A real life example for the absolute value function is a football field. Even though the center of the field is labeled zero, you wouldn't say you ran negative feet if you went backwards..

An example of a real life exponential function in electronics is the voltage across a capacitor or inductor when excited through a resistor. Another example is the amplitude as a function of frequency of a signal passing through a filter, when past the -3db point.
vCell phone plans: •A mobile provider charges a base rate of 40$ a month for service •The user is charged $.20 a minute for every minute used What is the linear equation for this example? Y = .20X +40
A real world example of a cubic function might be the change in volume of a cube or sphere, depending on the change in the dimensions of a side or radius, respectively.
A real life example of the sine function could be a ferris wheel. People board the ride at the ground (sinusoidal axis) and the highest and lowest heights you reach on the ride would be the amplitudes of the graph.

Real Life Application Linear Function Introduction to Linear function: Linear function is a polynomial function that has only one variable with first degree . We can also say that the linear function y has the variable x as its input .The linear function can be graphed as a straight line in the Cartesian plane. In the linear function x is called as domain and y is called as range. A linear function is a mathematical function in which the variables appear only in the first degree, are multiplied by constants, and are combined only by addition and subtraction. A linear function with single variable is represented by f(x)=ax+b where a and b are real numbers. When a linear function is written in the form Ax + By = C, it is said to be in standard form.The graph of a linear function is a straight line. Linear functions are used to model situations that show a constant rate of change between 2 variables. For example, the relation between feet and inches is always 12 inches/foot. So a linear function would be y = 12 x where y is the number of inches and x is the number of feet. y = 24 x models the number of hours in any given number of days {x}. Linear equations model the relationship between two variables and the effect that a change on one variable has on the other. In other words, the function changes in constant ratio to the change in the independent variable. This ratio can be used to interpolate or extrapolate to draw necessary conclusions. Real Life Application Linear Function: Lot of real application of linear functions is always around us. We can found many examples of linear functions in our every day life. The following are the some example of real life linear function applications. Temperature conversion (C=(F - 32)/1.8) Money exchange rate. Feet and inches conversion ( f = 12i) If a mobile network company charge a startup amount of $30 and then $.03 for each minute then the function is y = .03 x + 30 etc. Let us see some real world problems on linear function. Example Problems on Linear Functions: Q:1 Convert the temperature 50C into Fahrenheit by using the linear function Sol: Given temperature = 50C We need to convert the temperature from celsius into fahrenheit We know that , C=(F - 32)/1.8 To find the fahrenheit , solve for F. C=( F - 32 )/1.8 Multiply by 1.8 on both sides, 1.8C = F - 32 Add 32 on both sides, 1.8C + 32 = F F = 1.8C + 32 Substitute C = 50 in the above equation, F = 1.8(50) + 32 F = 90 + 32 F = 122 Answer: 50C = 122F Q:2 If a mobile network company charge a startup amount of $30 and then $.03 for each minute then find the amount for 10 minutes Sol: Given, Charge at startup = $30 and then $ 0.03 for each minute. We need to find the amount for 10 minute. Before that we need to form the linear function. y = 0.03 x + 30 Here y is amount and x is number of minutes. Substitute x = 10 . y = 0.03(10) + 30 = 0.3 + 30 = 30.3 The total amount for 10 minutes is $30.3 Answer: The total amount for 10 minutes is $30.3
