To find f(2) for the function f(x) = 3x² + 2x + 7, we need to substitute the value of x with 2 into the function.
Here’s how to do it step by step:
- Substitute x with 2:
f(2) = 3(2)² + 2(2) + 7
- Calculate (2)²:
f(2) = 3(4) + 2(2) + 7
- Now multiply:
f(2) = 12 + 4 + 7
- Finally, add the numbers:
f(2) = 12 + 4 + 7 = 23
Thus, the value of f(2) is 23.
