MA19.7A.25
Find approximate solutions by graphing the functions, making tables of values, or finding successive approximations, using technology where appropriate.

Note: Include cases where $f(x)$ is linear and $g(x)$ is constant or linear. [Algebra I with Probability, 19 edited]

Unpacked Content

Knowledge

Students know:

how to use a table to graph and analyze a function.
Estimate values between points on a table and graph.

Skills

Students are able to:

find and make use of successive approximation as method to solve the system y = f(x) and y = g(x)

Understanding

Students understand that:

to be more precise with solutions to a system of linear equations, it is best to make use of successive approximation (even using adequate technology) rather than one estimate based on a single representation.
