Vertical stretch occurs when a function value is multiplied by a number greater than 1.
For a function f(x), m*f(x) stretches f(x) in y direction if m is greater than 1.
From the given options we can see only A option lists such a case where an exponential function is being multiplied by a number greater than 1.
So, the answer to this question is A
These are the answers I think may be correct:
- 60 ways
- 45
- 30/53 chance
Answer:
If the diameter of a microscope's field is 0.12mm, how wide is an object that fills one-quarter of the field? (Explain how you've reached your answer.)

Step-by-step explanation:
Using exponential function concepts, it is found that the daily rate of change in the mass of the sample is of -4%, that is, the amount decays by 4%.
<h3>What is an exponential function?</h3>
A decaying exponential function is modeled by:

In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem, the function is:

Hence:


1 - r < 1, hence the rate is negative, and the daily rate of change in the mass of the sample is of -4%.
