How to Find f(2) for the Function f(x) = 3x² + 2x + 7?

To find f(2) for the function f(x) = 3x² + 2x + 7, we need to substitute x with 2 in the function’s equation.

Begin by plugging in 2:

f(2) = 3(2)² + 2(2) + 7

Now, calculate the components:

  • First, calculate (2)², which equals 4.
  • Next, multiply this by 3: 3 * 4 = 12.
  • Then, calculate 2(2), which equals 4.
  • Finally, we add the constant: 7.

Putting it all together:

f(2) = 12 + 4 + 7 = 23

Therefore, the value of f(2) is 23.
