What is f[g(4)] for the following functions?

f(x) = 2x2− 5

g(x) = 3x − 7

f[g(4)] = 74
f[g(4)] = 45
f[g(4)] = 27
f[g(4)] = 5

The right answer is: f[g(4)] = 45

Step-by-step explanation:

First of all, we have to find g(4)

So,

[tex]g(4) = 3(4)-7\\= 12-7\\=5[/tex]

Now to find f(g(4)) we will put the value of function g on 4 in place of x in function f

[tex]f(g(x)) = 2(g(4))^2-5\\= 2(5)^2 -5\\= 2(25) -5\\= 50-5\\=45[/tex]

Hence,

The right answer is: f[g(4)] = 45
