Question

the graph shows the number of internet users worldwide, y, in billions, x years after 2007. which of the following is closest to the number of internet users worldwide, in billions, 5 years after 2007?
a. 1.4
b. 2.4
c. 3.4
d. 4.4

Explanation:

Step1: Analyze the graph (assuming a linear or trend - from the points, we can see the pattern of increase. Let's assume we can estimate the value at x = 5 (5 years after 2007). From the given options and the trend of the graph (the points seem to be increasing, and at x = 5, we need to find the closest y - value.

Looking at the options, we can also think about the slope or the trend. If we consider the general trend of internet user growth, and from the graph's points (even though the graph is a bit obscured, the options are 1.4, 2.4, 3.4, 4.4). After 5 years, the growth should be such that 3.4 is a reasonable estimate (as 1.4 is too low, 2.4 might be for a lower x, 4.4 might be too high, and 3.4 fits the trend of growth over 5 years).

Step2: Compare with options

We check the options: a is 1.4 (too low), b is 2.4 (might be for x = 2 or 3), d is 4.4 (too high), c is 3.4 which is a reasonable estimate for x = 5.

Answer:

c. 3.4
