solve first derivative of f(x)=-460+100Q-Q2 where Q=10

• Math -

If:

f(x)= -460+100Q-Q^2

Then:

f´(x)=df/dQ=100Q+2Q=2*(50+q)

For Q=10

f´(x)=2*(50+10)=2*60=120

• Math -

f(Q)= -460+100Q-Q^2

not f(x)

• Math -

and

f´(Q)=df/dQ=100Q+2Q=2*(50+q)

f´(Q)=2*(50+10)=2*60=120

• Math -

f´(Q)=df/dQ=100+2Q=2*(50+q)

f´(Q)=2*(50+10)=2*60=120
