If you horizontally compress exponential function f(x)=2^x by a factor by a of 5, which of these is the equation of the new func
tion?
2 answers:
Answer: A.
Step-by-step explanation:
When we compress a function by a scale factor of 'k', where k >1, then the function after compression will become :
, where k>1
Given: Exponential function:
The scale factor of the compression (k): 5
Then after horizontally compression , the exponential function will become :

Step-by-step explanation:
We are given the following in the question:
Let be the proportion of the internet sales and
be the proportion of the store sale.
Hypothesis:
We have to conduct a hypothesis to check that the Internet sales are more than 10 percent higher than store sales.
Thus, we can design the null and alternative hypothesis as:
Alternate Hypothesis:
The alternate hypothesis states that the proportion of the internet sales is greater than the proportion of store sales by 10 percent.
