Intermediate Value Theorem
Step-by-step explanation:
Intermediate value theorem is one which states that f is a continuous function whose domain contains intervals which are a and b. It takes on any value between f(a) and f(b) at some point within interval. If we know the two values, we can pick any number between those two values and determine its function.

Answer: 239
Step-by-step explanation:
![g(7)=2(7)-5=9\\\\f[g(7)]=f(9)=3(9)^2 - 4=239](https://tex.z-dn.net/?f=g%287%29%3D2%287%29-5%3D9%5C%5C%5C%5Cf%5Bg%287%29%5D%3Df%289%29%3D3%289%29%5E2%20-%204%3D239)
