College Algebra, Chapter 2, 2.2, Section 2.2, Problem 4

a.) If a graph is symmetric with respect to the $x$-axis and $(a,b)$ is on the graph, then $\left(\underline{\phantom{x}a\phantom{x}}, \underline{\phantom{x}-b\phantom{x}}\right)$ is also on the graph
b.) If a graph is symmetric with respect to the $y$-axis and $(a,b)$ is on the graph, then $\left(\underline{\phantom{x}-a\phantom{x}}, \underline{\phantom{x}b\phantom{x}}\right)$ is also on the graph
c.) If a graph is symmetric with respect to the origin and $(a,b)$ is on the graph, then $\left(\underline{\phantom{x}-a\phantom{x}}, \underline{\phantom{x}-b\phantom{x}}\right)$ is also on the graph
