One later institution question and answer inquired students to state what they believe is the most important element for a student to do if they wanted to accomplish success. One that response stood out from the rest was practice. People who surely are successful do not become successful by being born. They work hard and dedicate their lives to succeeding. If you wish to reach your goals, keep this in mind! Below are one of the answer and question example that you possibly will utilize to practice and supercharge your practical knowledge and also give you insights that could help you to preserve your study in school.
Question:
Which function represents a vertical stretch of an exponential function? A. f(x)=3(1/2)^x B. f(x)=1/2(3)^x C. f(x)=(3)^2x D. f(x)=3^(1/2x)
Answer:
Answer:
A. f(x) = 3*(1/2)^x
Step-by-step explanation:
We know that, a function can be stretched or shrinked both horizontally and vertically.
Now, according to our question we are required to look at the vertical stretch of an exponential function.
The general form for a vertical stretch of a function f(x) is k*f(x) where k>1.
So, we compare this form with the options provided.
We see that in option A the exponential function is multiplied by 3 and so the function will be stretched vertically.
Hence, option A is correct.
They may hopefully help the student take care of the question by working with the questions and answer examples. Then could definitely have some sharing in a group discussion and also learning with the classmate relating to the topic, so another student also have some enlightenment and still keeps up the school learning.
