Int 1 Domain & Range, Functions, and Solving Equations Review

Front

What is the DOMAIN?

Back

The set of all possible input values (x-values) for a function.

Front

What is the domain of the graph?

Back

The range of x-values that the graph covers.

Front

What is the domain of this function?

Back

The set of x-values for which the function is defined.

Front

Solve for x: 5x + 4 = 3(2x - 5) - (x + 5)

Back

No Solution

Front

Find y if x=2: y = x^2 - 1

Back

y = 3

Front

What is the RANGE?

Back

The set of all possible output values (y-values) for a function.

Front

How do you determine the domain of a function?

Back

Identify the values of x that do not cause division by zero or negative square roots.

Front

What does it mean if a function has no solution?

Back

There are no values of x that satisfy the equation.

Front

What is an example of a function with a restricted domain?

Back

f(x) = 1/(x-2) has a domain of all real numbers except x=2.

Front

What is the difference between a function and a relation?

Back

A function assigns exactly one output for each input, while a relation can assign multiple outputs.
