Math Problem Statement

Jika diketahui f(x) = 3x^2 + 52x - 3, maka tentukan apakah f(x) termasuk dalam fungsi ganjil, genap, keduanya atau tidak keduanya!

Solution

The problem asks to determine whether the function f(x)=3x2+52x3f(x) = 3x^2 + 52x - 3 is odd, even, both, or neither. Here's how we solve it:

Step 1: Define what it means for a function to be even or odd:

  • A function is even if f(x)=f(x)f(-x) = f(x) for all xx.
  • A function is odd if f(x)=f(x)f(-x) = -f(x) for all xx.

Step 2: Calculate f(x)f(-x)

For the given function f(x)=3x2+52x3f(x) = 3x^2 + 52x - 3, substitute x-x into the function: f(x)=3(x)2+52(x)3=3x252x3f(-x) = 3(-x)^2 + 52(-x) - 3 = 3x^2 - 52x - 3

Step 3: Compare f(x)f(-x) with f(x)f(x)

  • f(x)=3x2+52x3f(x) = 3x^2 + 52x - 3
  • f(x)=3x252x3f(-x) = 3x^2 - 52x - 3

Clearly, f(x)f(x)f(-x) \neq f(x), so the function is not even.

Step 4: Check if f(x)=f(x)f(-x) = -f(x)

Now, check if f(x)f(-x) is the negative of f(x)f(x): f(x)=(3x2+52x3)=3x252x+3-f(x) = -(3x^2 + 52x - 3) = -3x^2 - 52x + 3 Clearly, f(x)f(x)f(-x) \neq -f(x), so the function is not odd.

Conclusion:

The function f(x)=3x2+52x3f(x) = 3x^2 + 52x - 3 is neither even nor odd.
