What is the slope of the curve f(x)=-3/4x^2 at the point (4, -12)?

to find the slope of the tangent line to the curve at the point  , we can first differentiate  with respect to .using the power rule for differentiation, which states thatwe can differentiate as follows: the derivative function gives you the slope of the tangent line to the graph of  at whatever x-value you put in (so tangent line to the point  on the graph of  )the point (4,-12) has the x-value of 4.so plug in 4 into the derivative function.so the slope of the tangent line to the curve at the point  is 

If your asking how much altogether for 12 performance the answer will be 98,496.
