Algebra Examples:
*Determine whether the correspondence is a function.
*Determine whether the relation is a function. Identify the domain and range.
{(3,1),(5,1),(7,10}
{(5,0),(3,-1),(0,0),(5,-1),(3,-2)}
*Given that g(x)=(x-4)/(x+3), find each of the following.
g(5), g(-3), g(x+h)
*A graph of a function is shown. Use the graph to find the indicated values.
*Determine whether the graph is that of a function.
*Find the domain of the function.
f(x)=4 - 2/x
*Determine the domain and range of the function.
