Evaluate the function f(x)=3x+12 with x+6. f(x+6) = 6x + 60

f(x+6) = 2x - 30

f(x+6) = 3x + 30

f(x+6) = 30

Answers

Answer 1
Answer:

Answer:

f(x+6)= 3x + 30

Step-by-step explanation:

Whenever you have to evaluate a function with a certain value, replace the variable x with a certain value. In this case, substitute x with the value of (x+6). You get the equation f(x+6)= 3(x+6) + 12, which simplifies into f(x+6)= 3x + 18 +12, which further simplifies into f(x+6)= 3x + 30.
