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.

What is the general form of a linear function?

Back

The general form of a linear function is f(x) = mx + b, where m is the slope and b is the y-intercept.

Front

What is the slope of the function f(x) = -2x + 13?

Back

The slope is -2.

Front

What is the y-intercept of the function f(x) = -2x + 13?

Back

The y-intercept is 13.

Front

How do you find the output of a function for a specific input?

Back

Substitute the input value into the function's equation and simplify.
