Select the correct answer from each drop-down menu. The table represents function f, and the graph represents function g.

x -2 -1 0 1 2 3 4
f(x) 7 0 -5 -8 -9 -8 -5

The line of symmetry for function f is
and the line of symmetry for function g is
.

The y-intercept of function f is
the y-intercept of function g.

Over the interval [2, 4], the average rate of change of function f is
the average rate of change of function g.
