Evaluating Functions (CP)

Front

What is a function?

Back

A function is a relation that assigns exactly one output for each input. It can be represented as f(x), where x is the input.

Front

What does f(x) represent in a function?

Back

f(x) represents the output of the function for a given input x.

Front

Evaluate the function: f(x) = x + 3, find f(-5).

Back

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

Front

What is the value of f(0) if f(x) = x + 4?

Back

f(0) = 0 + 4 = 4.

Front

If f(x) = 2x, what is f(3)?

Back

f(3) = 2(3) = 6.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x) 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 (f(x)) that the function can produce.

Front

What does it mean to evaluate a function?

Back

To evaluate a function means to calculate the output value for a specific input.

Front

If f(x) = x^2, what is f(2)?

Back

f(2) = 2^2 = 4.

Front

What is the relationship between f(x) and y in a function?

Back

f(x) is often used interchangeably with y, representing the output of the function.
