Step-by-step explanation:
1) The other curve is
then the common points of both curves are x-intercepts, the roots of 

2). Then those intersection points are the upper and the lower limits. Plugging in to this formula for they belong to the interval [-1,1]:


C. 14.9 because the second number is 5 so you drop the seven and the 5 and round the 8 up to 9
