Answer: f(2) is 3.
Step-by-step explanation:
f(2) just means "what is the vale of the function, f, when x = 2? Look for x=2 and read the y value where the line crosses x=2, in this case, the y value is 3. So f(2) = 3.

[One could also determine the equation for the line. Provided below.]
The slope is -(1/2) and the y-intercept is 4:
y = -(1/2)x + 4
For x=2,
y = -(1/2)*(2) + 4
y = 3
y(2) = 3
Answer:
$35.50
Step-by-step explanation:
55.50-48= 7.5
2008-2005 = 3
7.5 divided by 3 = 2.5 per year
2005-2000 = 5 multipled by 2.5 = 12.5
48-12.5=35.5

Answer:
Proxima Centauri is 2.478 x 10¹³ miles from Sun.
Explanation:
Distance of Proxima Centauri to sun = 4.24 light years
1 light year = 5.9 x 10¹² miles.
Distance of Proxima Centauri to sun in miles = Distance in light years x 5.9 x 10¹² miles
So, Distance of Proxima Centauri to sun in miles = 4.2 x 5.9 x 10¹² miles
= 2.478 x 10¹³ miles
So Proxima Centauri is 2.478 x 10¹³ miles from Sun.
