What does it mean for a function to be increasing?

Back

A function is increasing on an interval if, for any two points x1 and x2 in that interval, if x1 < x2 then f(x1) < f(x2).

Front

Define an even function.

Back

An even function is a function f(x) that satisfies f(-x) = f(x) for all x in its domain.

How do you find the 100th term of an arithmetic sequence?

Back

To find the nth term of an arithmetic sequence, use the formula f(n) = a + (n-1)d, where a is the first term and d is the common difference.

How can you determine if a function is even, odd, or neither from its graph?

Back

A function is even if it is symmetric about the y-axis, odd if it is symmetric about the origin, and neither if it does not have either symmetry.

What is the significance of the vertex in a quadratic function?

Back

The vertex of a quadratic function is the highest or lowest point on the graph, depending on the direction of the parabola.

Front

What does the term 'domain' refer to in a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.
