Im cramming for my cal test tomorrow, and im having a brain fart right now.(adsbygoogle = window.adsbygoogle || []).push({});

[10]

Heres a few problems on my Cal review i need some help with:

If f(5)=3 and f'(5)=2, use differentials to approx. f(5.01) - no clue what to do, i just need a point in the right direction

[7]

Let f(x) = x^3+2x^2-1 Suppose x = 2 and dx = 0.02

A) Calculate delta y

B) Calculate dy - already done

I solved part b using the equation dy=f'(x)dx but im stuck on part a
