Week 5 Discussion Questions What similarities and differences do you see between functions and linear equations studied in Ch. 3? An equation is a numeric expression with an equal sign. Moreover, a linear equation maps points onto the coordinate plane that can be connected. A function is an expression that for any value of x, there is one and only one value of y. In addition, a function can be a straight line (linear) or a curved line (non-linear). When we graph a linear equation it produces a straight line whereas, when we graph a function it can be any curve depending upon definition of function. Functions maps input (members of domains) and output (members of the range). Are all linear equations functions? No, every linear equation is not a function. Is there an instance when a linear equation is not a function? Support your answer. Yes, there is an instance when a linear equation in not a function. In order to be considered a function every x must have a unique y. A true function has to pass the vertical line test, which says if an expression is a function
