**A rectangular sign is being designed so that the length of its base, in feet, is 6 feet less than 4 times the height, h. Express the area of the sign as a function of h**

**Answer:**

4h2−6hLenght = l

Height = h

function = f(h)

L=4h-6

because area = l x h then :

f(h)=l x h

f(h)=(4h-6) x h

f(h)=4h2−6h
