P(x) = x 3 = 0 (because (x 3) is a factor of p(x)) therefore, p(-x) = -(x 3) = 0 = -x -3 =0 therefore,. -x = 3 x =. -3. ---------result 1 therefore, p(-x) = 3. --------------- result 2 now, p(x) p(-x) = x 3 3 = -3 3 3. ( by result 1 & 2) =. -3 6 =. 3

If p(x) = x + 3, then p(x) + p(-x) is equal toa)0b)3c)6d)2xCorrect ans...
To find the value of p(x) - p(-x), we need to substitute x and -x into the function p(x) = x^3.
Substituting x into the function, we get: p(x) = x^3
Substituting -x into the function, we get: p(-x) = (-x)^3 = -x^3
Therefore, p(x) - p(-x) = x^3 - (-x^3)
Simplifying the expression, we have:
p(x) - p(-x) = x^3 + x^3
Combining like terms, we get:
p(x) - p(-x) = 2x^3
So, the correct answer is d) 2x^3.
Explanation:
- Substituting x and -x into the function p(x) = x^3.
- Simplifying the expression by combining like terms.
- Concluding that p(x) - p(-x) = 2x^3.
