Unit 3 Mid Year Final Review

Front

What is the value of f(1) if f(x) is defined such that f(1) = 5?

Back

f(1) = 5

Front

What is the DOMAIN and RANGE of a function if the graph shows that y is greater than or equal to -3 for all real numbers x?

Back

DOMAIN: All real numbers; RANGE: y ≥ -3

Front

What is the range of the mapping if the output values are {1, 2, 4}?

Back

Range = {1, 2, 4}

Front

If a question asks you to find f(2), what does that mean?

Back

Let x = 2

Front

What is the DOMAIN and RANGE for a function if the graph shows that x is greater than or equal to -2 and y is greater than or equal to -3?

Back

DOMAIN: x ≥ -2; RANGE: y ≥ -3

Front

What does the term 'function' mean in mathematics?

Back

A function is a relation that assigns exactly one output for each input.

Front

What is the difference between DOMAIN and RANGE in a function?

Back

DOMAIN refers to all possible input values (x), while RANGE refers to all possible output values (y).

Front

How do you determine the DOMAIN of a function from its graph?

Back

The DOMAIN is determined by the x-values for which the graph exists.

Front

What does it mean if a function is defined for all real numbers?

Back

It means that there are no restrictions on the input values (x) of the function.

Front

What is the significance of the notation y ≥ -3 in a function's range?

Back

It indicates that the output values (y) of the function are greater than or equal to -3.
