Step-by-step explanation:
f(x)=3x3−21x2+36xf(x)=3x3-21x2+36x
Set 3x3−21x2+36x3x3-21x2+36x equal to 00.
3x3−21x2+36x=03x3-21x2+36x=0
by Solving for x
x=0,4,3
Hi there!
This is the way to solve this one-step equation:
5x=50
We divide both sides by 5 to isolate x:
x=10
Therefore, x=10. Hope it helps.

Answer not constant
Because the numbers are not consistent
This is exponential decay which can be expressed as:
y=ab^t, y=final value, a=initial value, b=rate, t=time
In this case a=25000, r=(100-20)/100=0.8 so
y=25000(0.8^t), so in 4.5 years...
y=25000(0.8^4.5)
y≈$9158.93 (to nearest cent)
