Which of the following functions would not model exponential decay? o a) h (x) 44 0.89o b) j (x) (0.34o c) b(x) 876 (1)o d z(x)- 7 (0.999)4x-2

Hello,
1^x=1
==>b(x)=876 is not a model exponential.

Answer C

The first answer is 45 because half of 90( a right angle) is 45
the second one is 45it says the angles are the same and bfc would be a half right angle which is 45 degrees
the last one is 90 degrees because it is next to a right angle which makes it automatically 90 degrees as well
