Final answer:
The question involves computing the convolution of two sequences for values of n from -2 to 5. The provided reference information is not directly related to the convolution operation required.
Step-by-step explanation:
The student is asking to compute the convolution y(n) = x(n) * h(n) for the given sequences x(n) and h(n). Convolution is an operation on two sequences of numbers that produces a third sequence expressing how the shape of one is modified by the other. The sequence x(n) is (1,2,4) with the first value corresponding to n=0, and sequence h(n) is (2,0,3) also with the first value corresponding to n=0. To compute the convolution for specific values of n, we perform the operation for n ranging from -2 to 5.
Unfortunately, the provided reference information doesn't directly apply to solving this problem, as it relates to general mathematics concepts that are not specifically about sequence convolution. So to properly answer this, we need to perform the convolution operation, which is outside the scope of the reference material provided.
