# 1. Given f(x, y, z)= x?y - yaz, find f(-1, 2, 3). 2. A storage building is planned which will have a rectangular base and a flat roof. The base will

1.Given f(x,y,z)=(x^2)y-(y^3)z, find f(-1,2,3)

2.A storage building is planned which will have a rectangular base and a flat roof. The base will cost \$10 per square foot. Each side will cost \$7 per square foot. The roof will cost \$8 per square foot. find the equation to express the construction cost of this building as a function of length x, width y, and height z

3.Given f (x,y,z)=ln((x^2)y-(y^3)z). find f/z and ^2f/yz

Hint: Simplify 1. Given f(x, y, z)= x?y - yaz, find f(-1, 2, 3).
