Semester 1 Algebra 1 Vocabulary Review

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

What does a positive slope indicate about a line?

Back

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

Front

What is a continuous graph?

Back

A continuous graph is a graph that consists of connected lines or curves, showing that the function has no breaks or gaps.

Front

What is the dependent variable in a graph?

Back

The dependent variable is the variable that is graphed on the y-axis and is affected by the independent variable.

Front

Which axis shows the independent variable?

Back

The x-axis shows the independent variable.

Front

What is the definition of a function?

Back

A function is a relation that assigns exactly one output value for each input value.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) that the function can accept.

Front

What does it mean if a slope is undefined?

Back

An undefined slope occurs in a vertical line where the x-value does not change, leading to division by zero.

Front

What is a linear equation?

Back

A linear equation is an equation that forms a straight line when graphed, typically in the form y = mx + b.

Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis, represented by the value of y when x = 0.
