Function properties from a graph
Use the graph to decide where the function is increasing or decreasing, whether it is bounded, what its maximum is and whether it is one-to-one.
Even and odd functions
Decide from the formula or from the graph whether a function is even, odd or neither.
Vertex and intercepts of a parabola
Complete the square to find the vertex of a parabola, its axis of symmetry and where the graph crosses the axes.
Match the equation to the parabola
Read the vertex, direction and width from the graph of a parabola and choose the correct formula.
Quadratic inequalities
Solve a quadratic inequality using its roots and the parabola, and choose the correct interval.
Absolute value functions and equations
Match a formula to the graph of y = |x − a| + b and solve equations with absolute value.
One-to-one and inverse functions
Decide whether a function is one-to-one, find the formula of the inverse function and points on its graph.
