Question

How do you find f(2) and f(0) given the expressions on the graph

Answer 1

Consider that the value of f(0) is given by the value of the y-coordinate, of the point on the line when x = 0.

Then, by checking the given graph, you have:

f(0) = -1

f(2) is given by the value of the y-coordinate of the point on the line when x = 2.

f(2) = -5
