Putting it All Together

Use the steps in the section "Finding Absolute Maximums and Minimums" to find the critical numbers for the functions below on the given intervals. Then find the absolute minimum and maximum as well. Report your answers as done for the example above just before Putting it All Together started.

$g(x)=x^4-3x^2+x,x$ in $-1\mathrm{.}5,1\mathrm{.}5$

$k(x)=x^{\frac{3}{4}}-sinx+\frac{1}{2},x$ in $0,2$
