Answer:
y=4x -9
Step-by-step explanation:
y intercept- where the line crosses the y-axis (-9)
Rise over run- 4
2. f(x) = x - 2x² - 5 + 10x
=-2x² + 8x - 5
f'(x)= -4x + 8
4. y = 100(45x - 30 - 3x³ + 2x²)
= 100(-3x³ + 2x² + 45x -30)
= -300x³ + 200x² + 4500x - 3000
y' = -900x² + 400x + 4500
240 because 2000x0.04=80 X3= 240
