Linear functions and equations

- The
**linear equations**we have graphed so far are in the form y= mx+b y = m x + b where m and b are real numbers. In this section we will graph**linear equations**that appear in different forms.**Linear equations**word problems: graphs Get 3 of 4 questions to level up! Graphing**linear**relationships word problems Get 3 of 4 questions to level up! **Linear Functions**. A**Function**is special relationship where each input has an output. A**function**is often written as f (x) where x is the input: 0 5 10 0 2 4 6 8 10 f (x) = x. Results from f (x) = x.- y = x², which has a standard width of a=1. The smaller the absolute value of a, the . wider the parabola will be. Use your calculator to graph the parent
**function**, y = x². Then, graph the following four quadratic**equations**on your calculator and compare their . widths to the standard width of the parent graph. 1. - Algebra. In the
**functions**section we talked about how a**function**is like a box that takes an independent input value and uses a rule defined mathematically to create a unique output value. The value for the output is dependent on the value that is put in the box.
