Let f (x ) = 3x² - 4 and let g (x) = 2x + 1. <br> Find the value of f[g(2)].
stepan [7]

Answer:

The value of f[g(2)] is 71.

Step-by-step explanation:

We need to find f[g(2)].

The first step is finding f[g(x)]

We have that:

f(x) = 3x^{2} - 4

g(x) = 2x + 1

To find f[g(x)], the first step is replacing each x is f by g(x). So

f(g(x)) = 3(2x+1)^{2} - 4

Now we replace x by 2

f(g(2)) = 3(2*2+1)^{2} - 4 = 75 - 4 = 71

The value of f[g(2)] is 71.
