(Q1) Which of the following is true about the function y = 3 • 2x?
Virty [35]

Answer: Third option

Step-by-step explanation:

You have the function:

y=3*2^x

Then, if the value of x increases by 1, you obtain:

-Rewrite the function:

y=3*2^{(x+1)}

-Substitute values for x into the function and observe what happen to y. Then:

x=1

y=3*2^{(1+1)}=12

x=2

y=3*2^{(2+1)}=24  

x=3

y=3*2^{(3+1)}=48  

The value of y is doubled.
