Question

Explain me how to used a graph on the function f(x) to find f(3)?

Answer 1

Just plug in 3 into the formula that you have been given and solve the equation.

Answer 2

Answer:

Sample Response: For f(3), the input is 3 and you are looking for the output. To determine the function's value when x = 3, go to the value of 3 on the x-axis and then locate the graph for that value of x. Determine the value of y from the y-axis at that location on the graph.
