Front

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

Back

To find the output, substitute the input value into the function rule and simplify.

Front

What is the function rule for the output when the input is increased by 3?

Back

The function rule is f(x) = x + 3.

Front

If the function rule is x ÷ 3, what is the output when the input is 12?

Back

The output is 4.

Back

It means to take the input value and multiply it by 7 to get the output.

Front

What is the function rule for a linear function?

Back

A linear function can be expressed in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you determine the slope of a linear function?

Back

The slope is determined by the ratio of the change in y to the change in x between two points on the line.
