Correct answer and explanation
Correct answer: f(x)
Explanation: ā Correct Answer: A) f(x) š Explanation: If you replace x with -x in the function f(x) = 5^x + 1/5^x + 2, the terms simply swap their positions. This results in the same mathematical expression as before. Because the result is identical, f(-x) is equal to f(x). This makes it an 'even' function in mathematics where the sign of the input does not change the total value.
