The value of f(-2.2) according to the given function; f(x) = [x] +3 is; f(-2.2) = 0.8

Graph of linear functions

According to the question;

  • The function represented by the graph is; f(x) = [x] + 3.

Hence, to evaluate the function at; f(-2.2);

We substitute -2.2 for x as follows;

  • f(x) = -2.2 + 3

  • f(x) = 0.8
