What is a function?

Back

A function is a relation between a set of inputs and a set of possible outputs where each input is related to exactly one output.

How can you determine if a graph represents a function?

Back

A graph represents a function if any vertical line drawn through the graph intersects it at most once (Vertical Line Test).

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise (change in y) over the run (change in x).

Front

What does a positive slope indicate?

Back

A positive slope indicates that as the x-values increase, the y-values also increase.

What does a negative slope indicate?

Back

A negative slope indicates that as the x-values increase, the y-values decrease.

What is the formula for finding the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula: m = (y2 - y1) / (x2 - x1).

What is the y-intercept of a function?

Back

The y-intercept is the point where the graph of the function crosses the y-axis (where x=0).

Front

Given the function f(x) = 3x + 2, what is f(1)?

Back

f(1) = 3(1) + 2 = 5.

What is the rate of change in a function?

Back

The rate of change is the ratio of the change in the output value to the change in the input value, often represented by the slope.

How do you find the value of a function at a specific point?

Back

To find the value of a function at a specific point, substitute the x-value into the function's equation.
