1. The problem statement, all variables and given/known data
Evaluate the divergence and curl of the following vectors.
A(r) is everywhere parallel to the y-axis with a magnitude A = cx + A0 , where c and
A0 are constants.

2. Relevant equations

3. The attempt at a solution
I can evaluate the div and curl, but i dont know how to work out what the actual vector is, so can anyone help me work out what the vector is?

$\vec{j}$ is "parallel to the y axis". $\vec{i}$ is parallel to the x axis. So any vector that is "always parallel to the y axis" must be of the form $A\vec{j}$.
