How do you evaluate the function f(x) = 2x² + 3x + 5 for the input value of 3?

To evaluate the function f(x) = 2x² + 3x + 5 for the input value of 3, you need to substitute 3 in place of x in the function.

Here are the steps to do so:

  1. Substitute 3 for x in the function:
  2. f(3) = 2(3)² + 3(3) + 5
  3. Now, calculate the value of (3)²:
  4. (3)² = 9
  5. Next, plug this value back into the function:
  6. f(3) = 2(9) + 3(3) + 5
  7. Calculate 2(9):
  8. 2(9) = 18
  9. Now calculate 3(3):
  10. 3(3) = 9
  11. Now, put everything together:
  12. f(3) = 18 + 9 + 5
  13. Add these values:
  14. 18 + 9 + 5 = 32

So, the value of the function f(x) at x = 3 is 32.
