8/ (1 1/2) = 36/x....8 muffins to 1 1/2 tsp = 36 ( 3 doz) muffins to x tsp this is a proportion, so we cross multiply (8)(x) = (1 1/2)(36) 8x = 3/2 * 36 8x = 108/2 8x = 54 x = 54/8 x = 6 3/4 <=== 6 3/4 tsps are needed to make 3 doz muffins
The question is simply asking you to evaluate the function for an input value of -3. Meaning we plug in -3 for all cases of n. (-3)^3 + (-3). This gives us -27 -3 which is -30. So g(-3)= -30
