Question

Which is a stretch of an exponential decay function?

Answer 1

f(x)=5/4(4/5)^x

Answer 2

f(x)=5/4(4/5)^x

Step-by-step explanation:

For example, a function stretch if it was multiplied by a number higher than 1. Assuming the base number is 1, if it becomes 5 then it is stretched. If the number become 1/5(less than 1) it is called compressed. Exponential decay function has ratio <1.
