ax^3-cx+7 = equation

a=7 c=21

Find the following limit.
lim h -> 0

f(x+h) - f(x) / h

1. First find the Simplified Difference Quotient (SDQ):

2. Now find the following limit:
lim h->0 SDQ=


This is my first week in Calculus. I have worked forever on these problems and cannot figure it out. I plan to get a math tutor ASAP, but until then.. I have hope with yahoo answers. Thanks guys!

please tell me the domain. I'm not quite sure here, but what i know is that the graph of a step function should be "stairs-like" but these are quite different. Please help? Thanks in advance.

methylated spirits. this is the information I know

Mass of empty cup: 2.2g (±0.05g)
Mass of cup with methylated spirits: 49.5g (±0.05g)
Mass of heated water: 44.8g (±0.05g)
Volume water: 50ml (±0.05ml)


Original temperature of methylated spirits: 20.0º (±0.5º)
Temperature of heated water: 80.0º (±0.5º)
Temperature of mixture: 54.0 º (±0.5º)

Specific Heat Capacity of a Mixture: MwaterCwaterΔTwater=MmethCmethΔTmeth

Assume specific heat capacity if water is 4.19 x 103 J/Kg-1K-1

i can solve the problem but i dont know how to take into account the the uncertanties to get relative uncertainty and percentage discrepency
