Answer 1

can anyone help please

Answer 2

with what?

Answer 3

to my question, I want to know how to get the answer

Answer 4

since you know that when x = 2, y = 8, when you replace x with xb:

\[8 = (xb)^{3}\]

x has been replaced by xb, so xb must equal 2

and then substituting in 0.5 for x, you can solve for b

\[0.5b = 2\]
