The answer is B.
Function means every x corresponds to one unique y value. ACD all have duplicates correspondence.
115 degrees because there are 180 degrees in a triangle so let the missing angle in the trinagle be x. Then we have x+75+40=180. Solving for x and subtracting that from 180 (supplementary angles) we get 115 degrees.
If a secant<span> and a </span><span>tangent of a circle </span><span>are drawn from a point outside the circle, then the product of the lengths of the secant and its external segment equals the square of the length of the tangent segment.
</span><span>
y</span>² = 7(15+7)
<span>y</span>² = 7*22
<span>y</span>² = 154
<span>y = </span>√154
<span>y = 12.4 </span>← to the nearest tenth<span>
</span><span>

1. 1st transformation is translation the parent function 
6 units to the right to get the function 
2. 2nd transformation is reflection the function 
over the x-axis. This transformation gives you the function 
3. 3rd transformation is vertical stretch of the function 
by a factor of 2 to get the function 
Only last two are present in options, then
answer: C and D.
It c) because it 56 out of 100
