Q2 Benchmark Review #1

Front

What is a function?

Back

A function is a relation where each input has exactly one output.

Front

How do you determine if a relation is a function?

Back

A relation is a function if no two ordered pairs have the same first element with different second elements.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

How do you solve the inequality -4x + 10 < 6x - 10?

Back

Add 4x to both sides: 10 < 10x - 10. Then add 10 to both sides: 20 < 10x. Finally, divide by 10: x > 2.

Front

What is the simplified form of √28?

Back

The simplified form of √28 is 2√7.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) that the function can accept.

Front

What does it mean for a function to be increasing?

Back

A function is increasing if, as the input values increase, the output values also increase.

Front

What does it mean for a function to be decreasing?

Back

A function is decreasing if, as the input values increase, the output values decrease.

Front

What is a linear function?

Back

A linear function is a function that graphs to a straight line and can be expressed in the form y = mx + b.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise over run (change in y over change in x).
