Analyze the end behavior of both functions.
igor_vitrenko [27]

Answer:

The end behaviour of all the functions is same ie they all tend to zero.

Step-by-step explanation:

In every option the function f(x)is a linear function which tends to infinity at the  end(as x tends to infinity).Now the function g(x)in every option is just the reciprocal of f(x).As we all know

\lim_{n \to \infty} f(x)=∞

then

\lim_{n \to \infty} 1/f(x)=0

Graph the six terms of a finite series where a1 = −3 and r = 1.5.
s344n2d4d5 [400]
We are given the first term and the common ratio, this means they belong to a geometric series.

For the given series:

a_{1}=-3 \\ &#10;r=1.5

Each term of the geometric series is obtained by multiplying the previous term by common ratio.

So the next terms will be:

-4.5, -6.75, -10.125, -15.1875, -22.78125

The general formula for the G.P would be:

a_{n}=-3(1.5)^{n-1}

On plotting the series, the result will be like this:
