💯Lesson 3.2 CFU

Front

Does this mapping diagram represent a function?

Back

Yes, because there are no repeating input values.

Front

What is f(1) if f(x) = 5?

Back

f(1) = 5.

Front

Given g(x) = 4x - 7, find g(-9).

Back

g(-9) = -43.

Front

Find f(10) if f(x) = -4x - 10.

Back

f(10) = -50.

Front

Find f(-2) if f(x) = 4x + 5.

Back

f(-2) = 3.

Front

What is a function?

Back

A relation where each input has exactly one output.

Front

What does it mean for a function to be linear?

Back

A function is linear if it can be graphically represented as a straight line.

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the output of a function?

Back

Substitute the input value into the function's equation.

Front

What is the domain of a function?

Back

The set of all possible input values (x-values) for the function.
