What is a function in mathematics?

Back

A function is a relation that assigns exactly one output for each input. It can be represented as an equation, a table, or a graph.

Front

What does the equation y = mx + b represent?

Back

This is the slope-intercept form of a linear equation, where m is the slope and b is the y-intercept.

Front

What is the slope of the line represented by the equation y = 4x?

Back

The slope is 4, which means for every 1 unit increase in x, y increases by 4 units.

Front

If x = 5, what is the output of the function y = 3x?

Back

The output is 15, since y = 3(5) = 15.

Front

What is the y-intercept in the equation y = 2x + 3?

Back

The y-intercept is 3, which is the value of y when x = 0.

Front

How do you find the output of a function?

Back

Substitute the input value into the function's equation and solve for the output.

Front

What is the function rule for the table that shows y = x + 2?

Back

The function rule is to add 2 to the input value x.

Front

What does the term 'input' refer to in a function?

Back

The input is the value you provide to a function to get an output.

Front

What is the output of the function rule x + 3 when the input is 4?

Back

The output is 7, since 4 + 3 = 7.

Front

What is the difference between a linear function and a non-linear function?

Back

A linear function creates a straight line when graphed, while a non-linear function creates a curve.
