Topic 3 Review - Algebra 1

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 result from using the function.

Front

What is the domain of a function?

Back

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

Front

Identify the range from the set: {-4, 0, 1, 3}.

Back

The range is {-4, 0, 1, 3}.

Front

Identify the domain from the inequality: -3 < x ≤ 3.

Back

The domain is the set of x-values that satisfy -3 < x ≤ 3.

Front

What does the notation |x| represent?

Back

|x| represents the absolute value of x, which is the distance of x from 0 on the number line.

Front

If y = |x| - 7, how does the graph transform?

Back

The graph slides down 7 units.

Front

What is the set of all y-values in a function called?

Back

The set of all y-values is called the range.

Front

What is the set of all x-values in a function called?

Back

The set of all x-values is called the domain.

Front

What is the output of the function f(x) = 2x + 3 when x = 1?

Back

f(1) = 2(1) + 3 = 5.

Front

What is the output of the function f(x) = x^2 when x = -2?

Back

f(-2) = (-2)^2 = 4.
