Answer the following questions for the function
f(x)=x√x2+1f(x)=xx2+1
defined on the interval −5≤x≤7-5≤x≤7.

f(x)f(x) is concave down on the interval x =     to x =    

f(x)f(x) is concave up on the interval x =     to x =    

The inflection point for this function is at x =    

The minimum for this function occurs at x =    

The maximum for this function occurs at x =

2)

Consider the function f(x)=12x5+15x4−240x3+7f

f(x) has inflection points at (reading from left to right) x = D, E, and F

where D is    
and E is    
and F is
