Question 1

Find the following for the given functions. For) = x2 s4. 90:) = W (a) (H mm = |:I (b) 0 mm = I: (c) (ngx) = I: (d) (5)00 = |:I What is the domain of 1? (Enter your answer using interval notation.) 9 I: A square concrete foundation is prepared as a base for a cylindrical tank (see figure). V1 LA I (a) Write the radius r of the tank as a function of the length x of the sides of the square. r(X) = D (b) Write the area A of the circular base of the tank as a function of the radius r. A(r) = D (c) Find and interpret (A a r)(x). U (A ., 000 = This represents the volume of the tank. This represents how the area changes as the length of the side x changes. This represents the area of the circular base of the tank on the square foundation with side length x. This represents the area of the edge of the tank. This represents howr the area changes as the radius r changes
