For the first one x must not = -3 because that would make the denominator zero.
second question This simplifies to u / (u+2)
She would be able to make 4 chocolate chip truffles.
I got my answer because, it takes 2 cups of chocolate chips to make 1 truffle and it takes 1 cup of cream but she has plenty cream.
The correct answer is B. The function has a constant rate of change, decreasing for all x at a rate of 6.
In order to find the rate of change, we have to identify the slope. The slope is always the coefficient of x when in slope intercept form. In this case it is -6, which means it decreases at a rate of 6.
The code at the end will be LEAP YEAR
you can use that to figure it out
