Finding directional derivatives

Problem

Let f, left parenthesis, x, comma, y, right parenthesis, equals, x, plus, 3, y, plus, 2. Suppose a, with, vector, on top, equals, left parenthesis, 0, comma, 0, right parenthesis and v, with, vector, on top, equals, left parenthesis, 2, comma, 3, right parenthesis.
Find the directional derivative of f, left parenthesis, x, comma, y, right parenthesis at a, with, vector, on top in the direction of v, with, vector, on top.
Do not normalize the direction vector for your calculation.
start fraction, \partial, f, divided by, \partial, v, end fraction, equals
