12-3-24 Bell Work: Evaluating functions

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 f(0) represent in a function?

Back

f(0) represents the output of the function when the input is 0.

Front

Evaluate f(0) if f(x) = -3 when x = 0.

Back

f(0) = -3.

Front

What does f(6) represent in a function?

Back

f(6) represents the output of the function when the input is 6.

Front

Evaluate f(6) if f(x) = 3x.

Back

f(6) = 18.

Front

What is the process to find x when y is given in a function?

Back

To find x when y is given, set the function equal to y and solve for x.

Front

If y = 18, find x in the function f(x) = 3x.

Back

x = 6.

Front

Evaluate f(2) if f(x) = 5x.

Back

f(2) = 10.

Front

What does it mean to evaluate a function?

Back

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

Front

If x = 1, what is y in the function f(x) = 2x?

Back

y = 2.
