Given the function f(x) = 2x² + 4x + 7, find f(4)

To find f(4), we need to substitute x with 4 in the function f(x) = 2x² + 4x + 7.

Here are the steps to calculate it:

1. Substitute x with 4 in the function: f(4) = 2(4)² + 4(4) + 7
2. Calculate (4)²: f(4) = 2(16) + 4(4) + 7
3. Multiply: f(4) = 32 + 16 + 7
4. Add them together: f(4) = 55

So, the final answer is f(4) = 55.
