[A.REI.11] Reasoning With Equations and Inequalities #11

Objective

Represent and solve equations and inequalities graphically. [Linear and exponential; learn as general principle.]

• • A.REI.11 Explain why the x-coordinates of the points where the graphs of the equations y = f(x) and y = g(x) intersect are the solutions of the equation f(x) = g(x); find the solutions approximately, e.g., using technology to graph the functions, make tables of values, or find successive approximations. Include cases where f(x) and/or g(x) are linear, polynomial, rational, absolute value, exponential, and logarithmic functions.
