Question

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

Answer 1

C=the value of x increases by 1, the value of y will double.

Explanation:

Answer 2

Answer: Third option

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.
