Answer:

[tex]\sf y= 2^x[/tex]

Step-by-step explanation:

The number of branches increases to the power of 2.  

When x = 1,

         y = 2 which is equal to 2¹ = 2

When x = 2,

         y = 4 which is equal to 2² = 2 * 2 * 2 = 4

When x = 3

        y = 8 which is equal to 2³ = 2 *2 * 2 = 8

Equation,

       y = 2ˣ
