Front

What is the domain of a function?

Back

The domain of a function is the set of all possible x values (inputs) for which the function is defined.

Front

What is the equation for the function g(x) if f(x) = x^3 and g(x) is a transformation of f(x)?

Back

g(x) = (x - 1)^3, which represents a horizontal shift of the function f(x) to the right by 1 unit.

What are x-intercepts?

Back

X-intercepts are the points where the graph of a function crosses the x-axis, which occur when y = 0.

Front

How do you find the x-intercepts of a quadratic function?

Back

To find the x-intercepts of a quadratic function, set the function equal to zero and solve for x.
