There are a few ways to answer. The simplest of which is to simply say "angle 1" which is written as or you can say "angle ELS" or "angle SLE" written as
and
respectively. All three of these angles represent the same idea.
It might help if you used a different color marker to help see what's going on. In figure 1 (see attached image), I've marked angle ALS in green. Then if you take out angle 2 from the angle ALS, then you'll be left over with just angle 1. Angle 2 is marked in blue and angle 1 is marked in red. This is shown in figure 2.

Answer:
C f(x) = {4e^x -5, ..., -x +7, ...
Step-by-step explanation:
The easiest portion to check is the constant section in the interval [0, 6]. All of the function definitions agree on that, so that doesn't help choose the right answer.
__
Next easiest is the linear section at the right. It has a negative slope. Extension of the line to the y-axis shows it has a positive y-intercept. This eliminates choices A and D.
__
The horizontal asymptote of the exponential portion at the left is -5. Both of the remaining choices B and C agree on that. The exponential is increasing at an increasing rate, so its coefficient is positive. This eliminates choice B.
The appropriate description of the function on the graph is offered by choice C.
_____
The graph below plots the function. We note that the given graph seems to show the exponential curve incorrectly.
