Unit 1 IA Midyear Final Review

Front

What is the range of the set of ordered pairs: (2, 11), (9, -3), (7, 21), (-8, 6)?

Back

The range is \{ -3, 6, 11, 21 \}.

Front

Evaluate f(-5) if f(x) = -2x - 12.

Back

f(-5) = -2(-5) - 12 = 10 - 12 = -2.

Front

What does slope represent in a linear function?

Back

Slope is another word for Rate of Change.

Front

What is the range of the function if the domain is 0 ≤ x ≤ 9?

Back

The range is 0 ≤ y ≤ 9.

Front

Which inequality best represents the domain of a water tank draining over time?

Back

0 < x < 20.

Front

Define 'range' in the context of a function.

Back

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

Front

What is the formula for calculating slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = \frac{y2 - y1}{x2 - x1}.

Front

What is the y-intercept of a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis (x=0).

Front

How do you find the domain of a function?

Back

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

Front

What is the difference between a function and a relation?

Back

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