# Which function represents a reflection of ƒ(x) = 2x?

Students were asked over to answer a question at academics and to declare what is most important for them to succeed. From the numerous results, the one that that stood out was practice. Successful people were not born successful; they become successful with hard work and dedication. This is how you can achieve your goals. the following some question and answer examples that you would possibly implement to further enhance your knowledge and gain insight that will help you to continue your school studies.

## Question:

Which function represents a reflection of ƒ(x) = 2x?

h(x) = 2^x + 1
h(x) = 2^x – 1
h(x) = 2^x – 1
h(x) = 2^-x

Step-by-step explanation:

Here the given function is,

Let (x,y) are the coordinates of the above exponential function,

By the rule of reflection about x-axis,

Thus, in the transformed figure that is obtained after the reflection about x-axis,

x is replaced by -x and y is replaced by -y,

Let h(x) = – f(x)

Hence, the transformed figure is,

Last Option is correct.

They could hopefully help the student resolve the question by obtaining the questions and answer examples. Then could actually make some sharing in a group discussion and also learning with the classmate in connection with the topic, so another student also take up some enlightenment and still keeps up the school learning.
