Part C
How does the of plants in five years compare to the expected number of plants in 15 years !Explain how these patterns could affect the method the gardener decides to use.
Answer:
f(x) = x³+2x²-16x-32
Step-by-step explanation:
f(x) = 0 when x = -4, -2, 4
So these are the roots
Factors are (x+4)(x+2)(x-4)
f(x) = [(x+4)(x-4)](x+2)
f(x) = (x²-16)(x+2)
f(x) = x³+2x²-16x-32
The answer is Y+1=-32(x-1)
