You can model the population of a certain city between the years 1965 and 1995 by the radical function P(x) = 75,000 ^3sqrt x-19

LuckyWell [14K]

Answer: B. 1975

Step-by-step explanation:

Given: The model of population of a certain city between the years 1965 and 1995 by the radical function

$P(x)=75000\sqrt[3]{x-1940}$

To find the x year at which population is 245,000, put this in equation we get

$245000=75000\sqrt[3]{x-1940}\\\\\Rightarrow\frac{245000}{17000}=\sqrt[3]{x-1940}\\\\\Rightarrow3.266=\sqrt[3]{x-1940}\\\\\Rightarrow\ x-1940=(3.266)^3..........\text{[by taking cube on both sides]}\\\\\Rightarrow\ x-1940=34.8587\\\\\Rightarrow\ x=1940+34.8587\\\\\Rightarrow\ x=1974.8587\approx1975$

Hence, at year 1975 the population of the city is 245,000.

Which graph shows a polynomial function, f, such that f(x)→ ∞ as x→ -∞ and f(x) →∞ as x→∞ ?

n200080 [17]

F(x) means y

so <span>f(x)→ ∞ as x→ -∞ and f(x) →∞ as x→∞ means
as x goes to the left </span><span>y goes up infinitely
as x goes the the right, y goes up intinitely

that would be the 4th graph
the parabola opening up </span>
