Honors Level 13 Functions Test Review

Front

What is a function?

Back

A function is a relation between a set of inputs and a set of possible outputs where each input is related to exactly one output.

Front

What does it mean for a function to be evaluated at a point?

Back

Evaluating a function at a point means substituting the input value into the function's equation to find the corresponding output.

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 find the x-intercepts of a function?

Back

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

Front

What is a vertical line test?

Back

The vertical line test is a method to determine if a curve is a function. If a vertical line intersects the curve at more than one point, it is not a function.

Front

What does f(x) = 16 mean?

Back

This means that the output of the function f for some input x is equal to 16. You need to find the x-values that satisfy this equation.

Front

What is the significance of the point (4, 16) on a graph of a function?

Back

The point (4, 16) indicates that when the input x is 4, the output of the function f is 16.

Front

What is the notation for the domain of a function?

Back

Front

What does it mean if a function is undefined at a certain point?

Back

If a function is undefined at a certain point, it means that there is no output value for that input, often due to division by zero or taking the square root of a negative number.
