Back

-3 < x ≤ 3

Front

Evaluate f(x) = x + 3 at x = -5. What is f(-5)?

Back

f(-5) = -2

What are all of the y values or outputs in a function called?

Back

Range

Front

What is the domain of a function that includes all real numbers?

Back

all real numbers

Front

What is the range of the function f(x) = 2x + 1?

Back

all real numbers (since it is a linear function)

Front

If a function has a domain of x ≥ 0, what does this imply about the function?

Back

The function is defined for all non-negative x values.

Front

What is the range of the function f(x) = x^2?

Back

y ≥ 0 (since squares of real numbers are non-negative)

Front

What does it mean for a function to be not a function?

Back

A relation is not a function if any x value is associated with more than one y value.

Front

If a function has a domain of -4 ≤ x < 5, what does this mean?

Back

The function is defined for x values from -4 to just below 5.
