Question

Fin d the elasticity of demand when the price is 4 for the demand function px^2=100
How would I find dx/dp ?

Answer 1

hmm they gave u the equation and i'm guessing P= price
we need to find dx/dp (take derivative ) when P = 4
\[\rm Px^2=100\] implicit differentation ?/

Answer 2

you got it ??
apply the product rule at the left side \[\rm f\cdot g = f g'+ gf'\]
so when you take the derivative of p
it would be \[\rm 1 \frac{dp}{dp}\] derivative of p with respect to dpp
makes sense ?? :P
