The factor theorem says that for a function f(x), if f(a) = 0, then (x - a) is a factor of f(x).
For f(x) = 2x^4 + 22x^3 + 60x^2
f(-5) = 2(-5)^4 + 22(-5)^3 + 60(-5)^2 = 2(625) + 22(-125) + 60(25) = 1250 - 2750 + 1500 = 0
Therefore, x - (-5) = x + 5 is a factor of f(x).
Answer: f(w) = 78,000 (0.97)^w
Step by step explanation:
The amount of fertilizer in the landscaping company's warehouse decreases by 3% per week
So,
3% ------> .03
now we subtract .03 from 1 and we get .97
1 - .03 = .97
and the function would look like this:
f(w) = 78,000 (0.97)^w
