Basic Functions and Their Graphs Section 1.2
Objectives • Determine if an equation gives y as a function of x . • Determine if a graph is a function. • Calculate a function value shown in function notation from an equation. • Calculate a function value shown in function notation from a graph. • Determine the domain and range (where possible) of a function given as a graph. • Calculate the x-intercepts and y-intercepts of a function from a graph.
Vocabulary • function notation • domain • range • x-intercept • y-intercept
Determine whether the equation defines y as a function of x.
Determine the indicated values of the function h shown in the graph
