The right answer is: f[g(4)] = 45
Step-by-step explanation:
First of all, we have to find g(4)
So,
![g(4) = 3(4)-7\\= 12-7\\=5](https://tex.z-dn.net/?f=g%284%29%20%3D%203%284%29-7%5C%5C%3D%2012-7%5C%5C%3D5)
Now to find f(g(4)) we will put the value of function g on 4 in place of x in function f
![f(g(x)) = 2(g(4))^2-5\\= 2(5)^2 -5\\= 2(25) -5\\= 50-5\\=45](https://tex.z-dn.net/?f=f%28g%28x%29%29%20%3D%202%28g%284%29%29%5E2-5%5C%5C%3D%202%285%29%5E2%20-5%5C%5C%3D%202%2825%29%20-5%5C%5C%3D%2050-5%5C%5C%3D45)
Hence,
The right answer is: f[g(4)] = 45
