that the sum of a rational number and an irrational number is
irrational; and that the product of a nonzero rational number and an
irrational number is irrational.
Define appropriate quantities for the purpose of descriptive
modeling.
Choose a level of accuracy appropriate to limitations on
measurement when reporting quantities.
Prove that, given a system of two equations in two variables,
replacing one equation by the sum of that equation and a multiple
of the other produces a system with the same solutions.
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.★

Recognize that sequences are functions, sometimes defined
recursively, whose domain is a subset of the integers. For example,
the Fibonacci sequence is defined recursively by f(0) = f(1) = 1,
f(n+1) = f(n) + f(n-1) for n ≥ 1.

For a function that models a relationship between two quantities,
interpret key features of graphs and tables in terms of the quantities,
and sketch graphs showing key features given a verbal description
of the relationship. Key features include: intercepts; intervals where
the function is increasing, decreasing, positive, or negative; relative
maximums and minimums; symmetries; end behavior; and
periodicity.★
Compare properties of two functions each represented in a different
way (algebraically, graphically, numerically in tables, or by verbal
descriptions). For example, given a graph of one quadratic function
and an algebraic expression for another, say which has the larger
maximum.
Distinguish between situations that can be modeled with linear
functions and with exponential functions.
a. Prove that linear functions grow by equal differences over equal
intervals, and that exponential functions grow by equal factors over
equal intervals.
Observe using graphs and tables that a quantity increasing
exponentially eventually exceeds a quantity increasing linearly,
quadratically, or (more generally) as a polynomial function.
Summarize categorical data for two categories in two-way
frequency tables. Interpret relative frequencies in the context of the
data (including joint, marginal, and conditional relative
frequencies). Recognize possible associations and trends in the
data.
