Please advise.

Function notation is very general. Students are unlikely to see how general it
is without a variety of examples. If the linear function is the only example,
forget function notation. To get it right, some students will need to see higher
polynomials, fractions, exponentials, and logarithms. If your primary interest
is the linear rationship, focus on it and leave functional notation for later.
IMHO Under no circumstances should functional notation be used without many
examples of functions besides the linear function.
