Given g(x)= 4x+4, find g(4)

Kipish [7]

$\large\underline{\bf\red{Solution:-}}$

Given that : g(x) = 4x + 4 .

So , in order to find the value of g(4) , just substitute x = 4 in the given function .

Here ,

=> g(x) = 4x + 4 .

=> g(4) = 4 × 4 + 4 .

=> g(4) = 16 + 4 .

=> g(4) = 20 .

Hence the required answer is 20.
