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.

How do you find the quotient of two functions f(x) and g(x)?

Back

To find the quotient of two functions, you divide the output of f(x) by the output of g(x): \( \left(\frac{f}{g}\right)(x) = \frac{f(x)}{g(x)} \).

What is the domain of the function f(x) = \frac{x}{x^2 - 4x - 12}?

Back

The domain is all real numbers except where the denominator is zero, which is (-∞,-2) u (-2,6) u (6,∞).

How do you determine the domain of a rational function?

Back

The domain of a rational function is all real numbers except where the denominator equals zero.

What is the significance of the leading term in a polynomial function?

Back

The leading term determines the end behavior of the polynomial function as x approaches positive or negative infinity.

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.
