Answer:
f(2) = 18
Option 4 is correct
Step-by-step explanation:
Given: f(x)=3(x+4)
To find: f(2)
The given function is linear function with variable x to find the value of function at x=2
So, put x=2 into the function and simplify it
f(x) = 3(x+4)
f(2) = 3(2+4)
f(2) = 3(6) [ multiply 3 and 6 = 18]
f(2) = 16
Hence, The value of f(2) is 18 of the given function.
