Based on the graphs of $f(x)$ and $g(x)$ below, answer the following questions. If a question has more than one answer, fill in your answer as a list of values separated by commas. Thus for example if you think $f(x) = g(x)$ when $x = 20$, when $x = 25$, and when $x = 29$, you would enter 20, 25, 29 (or any other order of these three numbers separated by commas).

(a) Find $f( 5.2 )$ =

(b) Fill in the blanks in each of the two points below to correctly complete the coordinates of two points on the graph of $g(x)$.
( 6.1 , )
( , 2.9 )

(c) For what value(s) of $x$ is/are $f(x) = 2.9$?
$x =$

(d) For what value(s) of $x$ is/are $f(x) = g(x)$?
$x =$
