Réponse:

Le domaine est l'ensemble de tous les nombres réels

La plage est y\leq 16

Explication étape par étape:

f(x)=-x^2-2x+15

Le domaine est l'ensemble des valeurs x pour lesquelles la fonction est définie

Dans f(x), nous avons des valeurs y pour toutes les valeurs x, donc il n'y a pas de restriction pour x

Ainsi, le domaine est l'ensemble de tous les nombres réels

La plage représente l'ensemble de toutes les valeurs y pour lesquelles la fonction est définie

D'après le graphe de la fonction donnée f(x), le point maximum est le sommet à (-1,16)

La plage de la fonction est y<=16

La plage est y\leq 16

Réponse:

Le domaine est l'ensemble des nombres réels

y ≤ 16

Explication étape par étape:

Le domaine est l'ensemble des valeurs x que le graphe couvre. Il n'y a aucune restriction sur les valeurs x. Le domaine est l'ensemble des nombres réels.

La plage est l'ensemble des valeurs y que le graphe couvre. Les valeurs y atteignent au maximum 16 au sommet de la parabole. Ainsi, la plage est y ≤ 16.

Matt invested $1500 into a stock of his choice. After two years, he had received
Leona [12618]

For this query, the time presented seems unclear to me. I understand that the rate of return is determined by total return over the investment. Assuming Matt received $400 as dividends without reinvesting them into additional shares, his total return across two years amounted to $500. Conversely, if the dividends were reinvested into the stock—something that typically happens with a 401(k) or IRA—his ROI would render a mere 6% due to only a $100 gain on a $1500 investment. In an actual market scenario, it’s likely that Matt would have experienced about a 5% return on a solid stock, while Bella would have had approximately 0.05% from a savings account.

I hope this was helpful!;)

zzz [12365]
FV = P(1 + r/t)^nt, where P denotes the principal amount, r is the interest rate, t is the frequency of compounding per year, and n is the total number of years.

Calculating: FV = 7650(1 + 0.05/4)^(9 x 4) = 7650(1 + 0.0125)^36 = 7650(1.0125)^36 = 7650(1.564) = $11,964.17
