#2: Tell whether the function below is linear or exponential. y = 4 • 2^x

Answers

O Linear
O Exponential

Exponential

Step-by-step explanation:

For this question you need to understand what is a linear function and what is an exponential function.

Linear function is a function where any variable x,y,z has the power of maximum 1 for example

x+y=1

7x+2y=10

1000x+9999y=40000

The numbers look too big but its the same category as linear function because all the variable in the equation are to the power of 1

Whereas, An exponential function is a mathematical function of the following form: where x is a variable, and a is a constant called the base of the function. Most commonly exponential functions are involved with mathematical symbol .

So in your question where x the variable has become the power/degree the fucntion is an exponential function.

its 4 because 2 times 2 is 4, if you double the number two you get four
