Which statement is true regarding the graphed functions? can someone me out?

f(2) = 0

g(2) = 0

you can see in graph f and g are 0 at x= 2 and x = -2 respectively

(x-4)^2 extended is x^2 - 8x + 16. then you substitute that in and you get x^2 - 8x + 16 - 28 = 8. 16-28= -12. then you subtract 8 on both sides. you get   x^2 - 8x - 12 - 8 = 0. -12-8=-20.   x^2 - 8x - 20 = 0. then you use the quadratic formula and you get the 2 answers.
