Which of the following is an even function?
- A \(\sqrt{x}\)
- B \(x^{2}+\sin ^{2} x\)
- C \(\sin ^{3} x\)
- D None of these
Answer & Solution
Correct Answer
(B) \(x^{2}+\sin ^{2} x\)
Step-by-step Solution
Detailed explanation
let \(f(x)=x^{2}+\sin ^{2} x\), then \(f(-x)=f(x)\) Therefore, \(f(x)=x^{2}+\sin ^{2} x\) is an even functions.
