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.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
