Front

Is this graph a function or not a function?

Back

A function is a relation where each input has exactly one output. If any vertical line intersects the graph more than once, it is not a function.

Front

What type of line is represented by the equation y = 10?

Back

The equation y = 10 represents a horizontal line where the y-value is always 10, regardless of the x-value.

Front

What is the Range of the linear function if the output values are between 0 and 6?

Back

The range of the function is 0 ≤ y ≤ 6, meaning y can take any value from 0 to 6 inclusive.

Front

Solve the equation: 4(-8x + 5) = -32x - 26. What is the solution?

Back

The equation has no solution, meaning there are no values of x that satisfy the equation.

Front

What is the y-intercept of a graph?

Back

The y-intercept is the point where the graph crosses the y-axis, represented as (0, y).

Front

What does it mean for a function to be linear?

Back

A linear function is a function that graphs to a straight line, characterized by the equation y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you determine if a relation is a function using the vertical line test?

Back

If a vertical line intersects the graph at more than one point, the relation is not a function.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0, indicating no change in y as x changes.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept indicates the starting value of y when x is 0, providing a reference point for the graph.

Front

What does it mean if a function has no solution?

Back

If a function has no solution, it means there are no values of the variable that satisfy the equation.
