We are given the graph of an equation, we are asked the following questions about that graph:
1. What is the domain?. The domain of a function is the set of values of the variable "x" that have a corresponding value f(x) in the function. In this case, the values of "x" are from -4 to 5, therefore, the domain is:
[tex]\text{Dom}=\lbrace x\parallel-42. What is the range?. The range of a function is the values of the y-variable function takes. In this case, the graph shows us that "y" takes values from y =-3 to infinity, this can be written mathematically as:[tex]\text{Range}=\mleft\lbrace y\parallel y\ge-3\mright\rbrace[/tex]
3. Where is the graph bounded?. The graph has a lower bound at y = -3 since no value of f(x) is smaller than -3
4. Where is the symmetry? This particular graph has no symmetry.
