What is an irrational number?

Back

An irrational number is a number that cannot be expressed as a fraction of two integers. Its decimal representation is non-repeating and non-terminating.

Identify the y-intercept of a function.

Back

The y-intercept of a function is the point where the graph of the function intersects the y-axis. It is found by evaluating the function at x = 0.

Front

What is a function?

Back

A function is a relation that assigns exactly one output for each input. In other words, for every x-value, there is one and only one corresponding y-value.

Front

How do you determine if a relation is a function from a set of ordered pairs?

Back

A relation is a function if no two ordered pairs have the same first element (x-value) with different second elements (y-values).

What is the formula for a linear function?

Back

A linear function can be expressed in the form f(x) = mx + b, where m is the slope and b is the y-intercept.

What is the significance of the y-intercept in a graph?

Back

The y-intercept indicates the starting value of the function when x = 0, providing insight into the function's behavior.

Front

What does it mean for a function to be linear?

Back

A linear function is one that graphs to a straight line, meaning it has a constant rate of change (slope) and can be represented by a linear equation.

Front

What is the difference between rational and irrational numbers?

Back

Rational numbers can be expressed as a fraction of two integers, while irrational numbers cannot be expressed in this way and have non-repeating, non-terminating decimals.

Front

How can you find the slope of a linear function?

Back

The slope (m) of a linear function can be found using the formula m = (y2 - y1) / (x2 - x1) using any two points on the line.
