Answer 1

Answer:

  see the attachment

Step-by-step explanation:

f(x) = x defines a line with a slope of 1 (upward to the right). Only the bottom two graphs have such a line.

The inequality symbol ≥ means the function has this definition for the case when x = 1. That is, f(x) ≥ x for x≥1 means f(1) = 1. The solid dot means that point on the graph is a point that satisfies the function definition.

The graph at lower right is a graph that includes the point f(1) = 3, which is not the same function as the one in the problem statement.
