3.1.3. Given the equation of a function, find algebraically the domain of a function.
3.1.4. Form the sum, difference, product, and quotient of two functions.
3.2.1. Use the vertical line test to determine if a graph represents a function.
3.2.2. Obtain information about a function (domain, range, intercepts, coordinates of points) from its graph.
3.3.1. Determine from inspecting a graph whether the function represented by the graph is even, odd or neither.
3.3.2. Determine algebraically from the equation of a function whether the function is even, odd or neither.
3.3.3. Determine from the graph of a function the intervals over which the function is increasing, decreasing or constant.
3.3.4. Determine from the graph of a function the local maxima and local minima of the function.
