The expression represents a straight line equation of the form y=mx+c. where m is the slope and c is the y-intercept. From the given expression, m=1.10 and c=0 therefore since a(w)=1.10w+0 is a straight line equation, the domain of the equation will be: (-∞,∞) and the range will be: (-∞,∞) This is because the domain and range of the straight line is always (-∞,∞).
