A company collected data for the number of text messages sent and received using a text-message application since October 2011. The table shows the number of text messages sent and received in billions over time. The data can be modeled by a quadratic function. Which function best models the data?

A. n(t) = -0.002t^2 + 0.55t + 5.02

B. n(t) = 0.072t^2 - 0.15t + 2.73

C. n(t) = -0.002t^2 + 5.02

D. n(t) = 0.072t^2 + 2.73

B. n(t) = 0.072t^2 - 0.15t + 2.73

Step-by-step explanation:

Plot data as pair of coordinates where t =x and n(t)=y

Use a graph tool to plot the coordinate points and join the points with a smooth curve

From the answers, test for the function that fits the points as plotted on the tool.

In this case, the function that fits the plot of the data is ;

n(t) = 0.072t^2 - 0.15t + 2.73

step-by-step explanation:

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.
