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.

Front

What does the vertical line test determine?

Back

The vertical line test determines if a graph represents a function. If any vertical line intersects the graph at more than one point, it is not a function.

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the coefficient in a linear equation represent?

Back

The coefficient represents the rate of change or slope of the line in the context of the equation.

Front

What is a flat fee in a pricing model?

Back

A flat fee is a fixed charge that does not change regardless of the amount of service or product provided.

Front

What is a variable cost?

Back

A variable cost is a cost that changes in proportion to the level of goods or services produced.

Front

What does it mean for a function to be increasing?

Back

A function is increasing if, as the input values increase, the output values also increase.

Front

What does it mean for a function to be decreasing?

Back

A function is decreasing if, as the input values increase, the output values decrease.

Front

What is the meaning of the term 'initial value' in a function?

Back

The initial value is the value of the function when the input is zero, often represented as the y-intercept in a linear function.

Front

What is a horizontal translation in graphing functions?

Back

A horizontal translation shifts the graph left or right along the x-axis.
