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 (y=9, x= -2, x=2, y= -9) and the line of symmetry for function g is (x=1,y=7,x= -1,y= -7). The y-intercept of function f is (equal to, less than, greater than) the y-intercept of function g. Over the interval [2, 4], the average rate of change of function f is (greater than, equal to, less than) the average rate of change of function g.​
