<u>Given</u>:
Given that the function 
We need to determine the function to evaluate when x = -5.
<u>Function</u>:
The function is given two interval. The interval
means that x takes all values less than or equal to 3.
And the interval
means that x takes all values greater than 3.
We need to determine the function that takes the limit when x = -5.
From the two limits, the limit x = -5 lie in the interval
because the interval takes all x values less than or equal to 3.
Hence, the function is 
Thus, Option A is the correct answer.
Answer:

Step-by-step explanation:

Plug in 0 for y to find the x intercept:
7x +3(0)= -21
7x=-21
x= -3
Plug in 0 for x to find y intercept:
7(0) + 3y= -21
3y= -21
y= -7
Find the tangent of the angle, using the height (472) minus the elevated height of the camera (2) which would be 470 meters, and also the distance away from the shuttle, which would be 750. Opposite divided by adjacent would make the tangent 0.626...so using a triangle chart, the closest whole numbered angle 0.626 would be to is 32 degrees.
