4 - looking the graphs

f(4)  = 3

g (f(4)) = g(3) = 2

5 -

g(f(x))= 3(3x^2+2x-10)-3

= 9x^2+6x-30-3

= 9x^2 + 6x - 33

with what we know

2 = 9x^2 + 6x - 33

9x^2 + 6x - 35

quadratic formula
-b +- sqrt (b^2-4ac) / 2a

-6 +- sqrt(36+1260)/18

-6 +- 36 / 18

30/18 = 5/3

-42/18 = -7/3

x = 5/3 or -7/3
