Suppose the demand functions are given as $1 = 4 ' pi - . " and x3 = 3 . " . The budget constraint is pill + pal? = m . What can you deduce about the utility function from this information? Select one: a. It has a Cobb-Douglas form where the exponents of x1 and x2 have a ratio of 3:4. O b. It has a Cobb-Douglas form where the exponents of x1 and x2 have a ratio of 1:3. O c. The given information is not enough to infer the form of the utility function. O d. It has a linear form where the coefficients of x1 and x2 have a ratio of 1:4. X
