## What You Need To Know...

MAFS.912.A-REI.4.11 – Explain why the solution of y = f(x) and y = g(x) is the solutions of the equation f(x) = g(x).

1. The benchmark will be assessed using Equation Response, Multiple Choice Response, Multi-select Response, Table Response, Simulation Response or Open Response.
2. Items may require students to find solutions by using a graph, a table of values, or by successive approximations to a given place value.
3. Items are restricted to exponential with a rational exponent, polynomial of degree greater than 2, rational, absolute value, and logarithmic.
4. Items may require the student to know the role of the x-coordinate and the y-coordinate in the intersection of f(x) = g(x).
