Here are some terms concerning algebraic functions that appear on the SAT Subject Test in Math 2 Make sure you’re familiar with them If the meaning of any of these vocabulary words keeps slipping your mind, add that word to your flash cards

Domain The set of values that may be put into a function

Range The set of values that can be produced by a

function

Even Function A function for which f(x) = f(−x)—even functions

are symmetrical across the y-axis.

Odd Function A function for which −f(x) = f(−x)—odd

functions have origin symmetry, which means that they are the same when reflected across the origin

Root Values in a function’s domain at which the

function equals zero—a root is also called a zero,

solution, or x-intercept of a function.

Degree The sum of the exponents in an algebraic term—

the degree of a polynomial is the highest degree

of any term in the polynomial

Asymptote A line that the graph of a function approaches

but never reaches

Period In periodic functions, the distance traveled by

the function before it repeats itself

Frequency The number of times a graph repeats itself in a

given distance; the reciprocal of the function’s period

Amplitude In a periodic function, half the difference

between the least and greatest values of the function
