Answer 1

Option D is correct.

x y

0 5

1 10

2 20

Explanation:

Given the equation:
`y = 5(2)^x` .....[1]

Here, x is the input variable and y is the output variable.

For x =0

Substitute in equation [1]; we have;

`y = 5(2)^(0) = 5 \cdot 1= 5`

For x = 1

Substitute in equation [1]; we have;

`y = 5(2)^(1) = 5 \cdot 2= 10`

For x =2

Substitute in equation [1]; we have;

`y = 5(2)^(2) = 5 \cdot 4= 20`

Therefore, the table values which is correct for the equation
`y = 5(2)^x` is;

x y

0 5

1 10
