To find the value of f(3) for the function f(x) = 2x3 + 7, you need to substitute the value of x with 3 in the given function.
Here’s the step-by-step process:
- Start with the function: f(x) = 2x3 + 7
- Substitute 3 into the function for x: f(3) = 2(3)3 + 7
- Calculate 33: 33 = 27
- Multiply by 2: 2 * 27 = 54
- Add 7: 54 + 7 = 61
Therefore, the final result is:
f(3) = 61
