Let f be a differentiable function with f(1)=-2, f'(1)=1, f(3)=-3, and f'3)=3. Let the function g(x)=f(3x). Write the equation of the line tangent to the graph of g at the point where x=1.

im pretty sure its

step-by-step explanation:

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.
