Find dy/dx @ x = 1.
| 1. y = -7x + 5 1 -7 -1 |
2. y = x3 + 5 1 8 3 |
| 3. y = x 1 -1 0 |
4. y = x/3 + 5 1 0 1/3 |
| 5. y = 20 - 22x +
6x2 -32 32 -10 |
6. y = (5 + 3x2)3 1 4096 1152 |
| 7. y = (5 + 3x)(4 - 2x) 10 -10 1 |
8. y = (2x + 1) /
(x - 7) -3/4 -5/12 -1/4 |
| 9. For y = 1
/ x , find the equation of the line tangent @ x = 3. y - 1/3 = -1/9(x - 3) y - 3 = 1/3(x + 3) y = -1/3x + 3 |
10. Verify the derivative of y = 5x2 + 3x + 1 is 10x + 3 using the formal definition of derivative.(let h = delta x)
