In Class: Linear Unit Test Review

Front

What is the output in a function?

Back

The output is the value that results from applying the function to an input value.

Front

What does f(7) represent in a function?

Back

f(7) represents the output of the function when the input x is equal to 7.

Front

Evaluate the function: f(x) = -4x + 1; find f(-4).

Back

f(-4) = 17.

Front

What is the input in a function?

Back

The input is the value that is fed into the function to produce an output.

Front

Evaluate the function: f(x) = 3x + 2; find f(6).

Back

f(6) = 20.

Front

What is a linear function?

Back

A linear function is a function that can be graphically represented as a straight line, typically in the form f(x) = mx + b.

Front

What does the slope (m) represent in a linear function?

Back

The slope represents the rate of change of the function; it indicates how much the output (y) changes for a unit change in the input (x).

Front

What does the y-intercept (b) represent in a linear function?

Back

The y-intercept is the value of the output (y) when the input (x) is zero.

Front

How do you find the output of a function?

Back

To find the output, substitute the input value into the function's equation and simplify.

Front

What is the domain of a function?

Back

The domain is the set of all possible input values (x) for which the function is defined.
