Show answers and working
1. dy/dx = 12x^2 + 1
Multiply by the power, then reduce the power by 1. 4x^3 → 12x^2; 1x → 1.
2. dy/dx = 15x^2 + 7
Multiply by the power, then reduce the power by 1. 5x^3 → 15x^2; 7x → 7.
3. dy/dx = 20x^4 + 2
Multiply by the power, then reduce the power by 1. 4x^5 → 20x^4; 2x → 2.
4. dy/dx = 15x^2 + 1
Multiply by the power, then reduce the power by 1. 5x^3 → 15x^2; 1x → 1.
5. dy/dx = 20x^4 + 9
Multiply by the power, then reduce the power by 1. 4x^5 → 20x^4; 9x → 9.
6. dy/dx = 6x^1 + 8
Multiply by the power, then reduce the power by 1. 3x^2 → 6x^1; 8x → 8.
7. dy/dx = 9x^2 + 8
Multiply by the power, then reduce the power by 1. 3x^3 → 9x^2; 8x → 8.
8. dy/dx = 30x^4 + 4
Multiply by the power, then reduce the power by 1. 6x^5 → 30x^4; 4x → 4.
9. 11
dy/dx = 2x^1 + 9. At x = 1: 2 × 1 + 9 = 11.
10. 4
dy/dx = 3x^2 + 1. At x = 1: 3 × 1 + 1 = 4.
11. 2034
dy/dx = 25x^4 + 9. At x = 3: 25 × 81 + 9 = 2034.
12. 9
dy/dx = 5x^4 + 4. At x = 1: 5 × 1 + 4 = 9.
Worked examples
Differentiate y = 5x^4 + 5x.
- Multiply by the power, then reduce the power by 1.
- 5x^4 → 20x^3; 5x → 5.
- Answer: dy/dx = 20x^3 + 5
Differentiate y = 1x^2 + 5x.
- Multiply by the power, then reduce the power by 1.
- 1x^2 → 2x^1; 5x → 5.
- Answer: dy/dx = 2x^1 + 5
Find the gradient of y = 6x^5 + 1x at x = 2.
- dy/dx = 30x^4 + 1.
- At x = 2: 30 × 16 + 1 = 481.
- Answer: 481

Common mistakes
What learners typically get wrong, and how to fix it.
Forgets that a constant differentiates to 0.
Correction: Constants have zero gradient.
Reduces the power but forgets to multiply by it.
Correction: Multiply by the power, then reduce it by 1.
Teacher tips
- · Link to gradients of straight lines first.
Parent tips
- · Ask how speed relates to distance over time.
Real-life applications
- · Speed from distance, maximising profit.
