The question was 6-fold but the only part with the restriction was min and max values of y...everything else pertained to the original function.Thanks for staying with me...it's been a long day!

the original function was x^5-15x^3 +10 so when you figured the min and max with the restrictions and substituted 1, and 5 for the x's should you have included the constant 10? So I came up with (-4) and (1260), but forgive me I still don't know what that means...thes ...

So I am correct in my thinking the critical points are the (-3,175)(3 -152) because that was asked of the original function,.... because I only have to give only the max and min values for y if x is restricted to the interval {1,5}? Thanks again for all your help.
