Compute the derivative for the following: n(x) = sin(x^3-5x^2+4x-7) Thanks, andy

calculus
If I figured out average velocity can I use that to figure instantaneous velocity? There is no function. Thanks

calculus
Well thanks again for the help...and I am probably older than you...hence the mind gaps of my own!

calculus
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!

calculus
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 ...

calculus
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.

calculus
So I am ttinking the critical points are the (-3,175)(3, -152)

calculus
WOW! Thanks Much! Love that site you gave me and I totally understand and can plainly see it all except the max and min. I am seeing the max at (-3, 175) and the min at (3, -152) but does that satisfy "if x is restricted to the interval {1, 5)" because I thought that...

the graph (x^5-15*x^3 +10) is sketched without axes and not to scale. I found f'(x), set it to zero and got x=0, x=3, x=-3. these are critical numbers? I plugged them into original equation to find y (?) and got (0,10),3,-152)(-3, 172). I have to show for what intervals (...
