Question

Explain how to use the graph of the function f(x) to find f(3)

Answer 1

from 3 in x-axis, make vertical line untill intersect with the graph, from intersect point make horizontal line until intersect y-axis, the value in y-axis tje last intersection is f(3)

Answer 2

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.
