function that accepts vector

Can someone explain why I must use ".^" in the first function but then ".*" in the second? (for both to accept vectors and scalars) Why don't I use ".*" in the first?
f=(13/400)*(x.^3 - 30.876*x.^2 + 32.454*x + 99.89) g =(2*x.*exp(cos(6*x)).*exp(-x)) + 15

You asked virtually this same question before. You got multiple people explaining it to you then. Read the responses you received there.
