Q. Is the following function even, odd, or neither?\newlinef(x)=2x+3 f(x)=2^{x+3} \newlineChoose 11 answer:\newline(A) Even\newline(B) Odd\newline(C) Neither
  1. Symmetry properties of the function: To determine if the function f(x)=2(x+3)f(x) = 2^{(x+3)} is even, odd, or neither, we need to check the symmetry properties of the function. An even function satisfies f(x)=f(x)f(x) = f(-x) for all xx in its domain, and an odd function satisfies f(x)=f(x)f(-x) = -f(x) for all xx in its domain.
  2. Checking if f(x) is even: Let's first check if f(x) is even. We need to compare f(x) with f(-x). We have f(x) = 2(x+3)2^{(x+3)}. Now let's find f(-x) which is f(-x) = 2(x+3)2^{(-x+3)}.
  3. Comparing f(x)f(x) with f(x)f(-x): Now we compare f(x)f(x) with f(x)f(-x). If f(x)=f(x)f(x) = f(-x) for all xx, then the function is even. We have f(x)=2(x+3)f(x) = 2^{(x+3)} and f(x)=2(x+3)f(-x) = 2^{(-x+3)}. These two expressions are not equal for all xx because the exponents are not the same due to the sign change in xx. Therefore, f(x)f(x) is not an even function.
  4. Conclusion: f(x)f(x) is not an even function: Next, let's check if f(x)f(x) is odd. For f(x)f(x) to be odd, we need f(x)f(-x) to be equal to f(x)-f(x) for all xx. We already have f(x)=2x+3f(-x) = 2^{-x+3}. Now let's find f(x)-f(x) which is f(x)=2x+3-f(x) = -2^{x+3}.
  5. Checking if f(x)f(x) is odd: We compare f(x)f(-x) with f(x)-f(x). If f(x)=f(x)f(-x) = -f(x) for all xx, then the function is odd. We have f(x)=2x+3f(-x) = 2^{-x+3} and f(x)=2x+3-f(x) = -2^{x+3}. These two expressions are not equal for all xx because the negative sign outside the exponent does not change the exponent itself. Therefore, f(x)f(x) is not an odd function.
  6. Comparing f(x)f(-x) with f(x)-f(x): Since f(x)f(x) is neither even nor odd, the correct choice is (C) Neither.
