Identify function, Domain Range and evaluate

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

What is the range of a function?

Back

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

Front

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

Back

The domain can be determined by identifying the x-values that the graph covers.

Front

What is the domain of the function f(x) = 1/(x-2)?

Back

The domain is all real numbers except x = 2.

Front

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

Back

The range is all real numbers greater than or equal to 0.

Front

Evaluate f(-4) for the function f(x) = 2x + 3.

Back

f(-4) = 2(-4) + 3 = -8 + 3 = -5.

Front

What is the domain of the function f(x) = sqrt(x)?

Back

The domain is all real numbers x such that x ≥ 0.

Front

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

Back

The range is all real numbers y such that y ≥ 2.

Front

If the domain of a function is {-5, -4, -3, -1}, what are the possible outputs?

Back

The outputs depend on the function's rule applied to each input in the domain.
