Differentiate 4x^2 - 7
This derivative uses the power rule and the constant rule.
The constant term disappears after differentiation.
One structured route through this exact problem.
- 1Differentiate 4x^2 by multiplying 4 by 2 and reducing the power by 1.
- 2That gives 8x.
- 3Differentiate the constant -7 to get 0.
- 4So the derivative is 8x.
Use these quick checks before relying on the route.
- Make sure the constant term does not appear in the final derivative.
- Check that the power was reduced correctly from 2 to 1.
