This week in math we learned more about relations and functions. We reviewed how to write out inequalities and we also learned about domain and range. At first I was confused about the whole concept of the input and outputs but once I got used to solving more equations it got easier to do.
Domain: the independent(input) variable in the relation.
Range: the set of all numbers for the dependent(output) variable in the relation.
Function: a special realtion where every input(x) has only one output(y).
Function Notation:
To evaluate a function you would have to substitute the variable with the given number which in this case would be 5 and -8. To solve the equation remember to always use B.E.D.M.A.S!!
