centimeters of bacteria is in the dish and then continues to measure the area after
each hour. She put the data that she gathered into the table below.

If f(x)=2x-6 and g(x)=3x+9, find (f-g)(x)

Acompany produces packets of soap powder labeled “giant size 32 ounces.” the actual weight of soap powder in such a box has a normal distribution with a mean of 33 oz and a standard deviation of 0.7 oz. to avoid having dissatisfied customers, the company says a box of soap is considered underweight if it weighs less than 32 oz. to avoid losing money, it labels the top 5% (the heaviest 5%) overweight. how heavy does a box have to be for it to be labeled overweight?

Let f(x) = 5/x and g(x)=2x2+5x. what two numbers are not in the domain of f o g
