 Question 289929: Ok so I am so lost on this question can someone help me I have been trying to figure it out all morning. Let P=(x,y) be a point of the graph y=x2^-9. d(x)= What is d if x=0? What is d if x=1? For what positive value of x is d the smallest. This is jsut review before midterms but when I look at the schools examples I am not sure where the number that they have are coming from. Could someone break this down for me piece by piece? Thanks!
