4. Let y = f(x); 2: = jxx). Let y = f(x) = x5. metatttttmml? 5. Let y = VatZane x3). What is dy/dx? [Notez 3\\/x = (x2)1/3.] 6. Mass (measured in grams) can be expressed as volume at density, with volume measured in centimeters3 and density measured in grams per centimeter3. Suppose the volume (V) of a plant is increasing according to 100 + 121?, where t is measured in hours, and that the density (p) of the plant is decreasing according to 0.8 0. 051'. How does mass change as a function of time? [Hintz Product rule]
