Idk what end behavior for this?

Answer:
b
Step-by-step explanation:
The end behaviour is what happens when x gets larger and positive ( right hand end ) or larger and negative ( left hand end ) Tis is called the end behaviour as x → + ∞ and x → - ∞ respectively
For a polynomial the end behaviour is determined by the term of greatest degree.
For the given function
f(x) = - 3x³ + 2x + 4 ← degree 5 polynomial
The leading coefficient is positive
• Odd degree, positive leading coefficient, then
as x → - ∞, f(x) → - ∞
as x → + ∞, f(x) → + ∞
----------------------------------------------------------------------
• Odd degree, negative leading coefficient, then
as x → - ∞, f(x) → f(x) → + ∞
as x → + ∞, f(x) → - ∞

A is the correct option.
Answer:
Step-by-step explanation:
So the initial value of the business computer is $20,000. It depreciates by 15% per year. This is exponential decay. The standard function for exponential decay is:
Where <em>P </em>is the initial value, <em>r</em> is the rate of decay, and <em>t</em> is the time in years.
Since the computer decreases by 15% per year, this means that each year, the computer will be 1-15% or 85% than its previous value.
Therefore, the equation that models the value of the computer is:
