Function Tables

Front

What is a function in mathematics?

Back

A function is a relation that assigns exactly one output for each input from a set of inputs.

Front

What does the notation y = f(x) represent?

Back

It represents a function f that takes an input x and produces an output y.

Front

What is the purpose of a function table?

Back

A function table is used to organize input-output pairs for a function, helping to visualize the relationship between variables.

Front

How do you determine the output of a function given an input?

Back

To determine the output, substitute the input value into the function's equation and solve for the output.

Front

What is the slope of the function y = x + 2?

Back

The slope is 1, indicating that for every unit increase in x, y increases by 1.

Front

What is the y-intercept of the function y = x + 2?

Back

The y-intercept is 2, which is the value of y when x is 0.

Front

How do you find the missing number in a function table?

Back

To find the missing number, use the function's equation to solve for the unknown variable.

Front

What is the function of the table if y = x ÷ 3?

Back

The function describes a linear relationship where the output y is one-third of the input x.

Front

What is the function of the table if y = x + 7?

Back

The function describes a linear relationship where the output y is the input x increased by 7.

Front

What is the function of the table if y = x * 7?

Back

The function describes a linear relationship where the output y is seven times the input x.
