The function that could be a stretch of the exponential decay function shown on the graph is B. f(x) = One-half(6)x.
<h3>How to illustrate the function?</h3>
From the information given, it can be seen that function A is a monotonically increasing function.
Also, it can be seen that C and D don't pass through (0, 1).
Therefore, the function could be a stretch of the exponential decay function shown on the graph is B.

Ans:
1. m ∠C = 88°
2. m ∠B = 100°
3. m ∠A = 92°
4. m ∠D = 80°
Explanation:
∠A and ∠C are supplementary angles; therefore:
∠A + ∠C = 180° --- (A)
Since,
∠A = (x+2)°
and
∠C = (x-2)°
Plug-in the values in equation (A):
(A) => (x+2)° + (x-2)° = 180°
=> x° + 2° + x° - 2° = 180°
=> 2x° = 180°
=> x = 90°
Since x = 90°, therefore,
∠A = (x+2)° = 92°,
and
∠C = (x-2)° = 88°
Since ∠B and ∠D are supplementary angles; therefore,
∠B + ∠D = 180°
∠B + (x-10)° = 180°
Since,
x = 90°; therefore,
∠B + 80° = 180°
∠B = 100°
And since,
∠B + ∠D = 180°
and
∠B = 100°
Therefore,
∠D = 180° - 100°
∠D= 80°
