Front

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.

Front

Define an odd function.

Back

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

Front

What is the general form of a linear function?

Back

The general form of a linear function is y = mx + b, where m is the slope and b is the y-intercept.

Front

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.

Front

What is the slope of the line represented by the equation y = 2x + 3?

Back

The slope of the line is 2.

Front

What is the y-intercept of the equation y = -3x + 2?

Back

The y-intercept is 2.

Front

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.

Front

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.
