Question

Given the graph of f(x), fund the value of f(4).

Options: -1, 1, 2, 4

Answer 1

2

Explanation:

the y-value of an x-value of 4, according to the graph, is 2

Answer 2

2

Explanation:

This question is asking you to find the value of f(x) which is really just the y-coordinate. You need to find the y-coordinate for f(4), which means when x=4. So, go to the line on the graph where x=4 and find the point that lies there. In this case, when x=4 the y-coordinate is 2. The coordinates for this point are (4,2) and can be seen on the far right side of the graph.
