Hi, how do you find the first and second derivatives of the function. y=(x^2-7/63x) (x^4+1/x^3) i think for the first derivative dy/dx it's 2/63x-3/63x^-3+4/9x^-5 but i'm not sure, and i have no clue for the second derivative d^2y/dx^2.

Questions 7-8. use the following table to answer. year 2006 2007 2008 2009 2010 2011 2012 2013 cpi 201.6 207.342 215.303 214.537 218.056 224.939 229.594 232.957 7. suppose you bought a house in 2006 for $120,000. use the table above to calculate the 2013 value adjusted for inflation. (round to the nearest whole number) 8. suppose you bought a house in 2013 for $90,000. use the table above to calculate the 2006 value adjusted for inflation. (round to the nearest whole number)
