Question

F(x)=4x+2 find f(9)What is the output value (y)?

Option 1: 38
Option 2: 36
Option 3: 34
Option 4: 32

Answer 1

To determine the output value of f(9), substitute 9 into the function f(x) = 4x + 2, which gives f(9) = 38. This is Option 1.

Step-by-step explanation:

To find the output value of f(9) for the function f(x) = 4x + 2, we simply substitute 9 for x in the function and solve:

f(9) = 4(9) + 2

f(9) = 36 + 2

f(9) = 38

Therefore, the output value of f(9) is 38, which corresponds to Option 1.
