Answer 1

Answer:

a = 2  

b = 4

The equation is ⇒ $y=2(4)^{x}$

Step-by-step explanation:

∵ It is an exponential Regression

∴ y = $ab^{x}$ where a ≠ 0

∵ x = 0 ⇒ y = 2

∴ 2 = a$b^{0}$ ⇒ 2 = a(1) (where b^0 = 1)

∴ a = 2

∵ x = 1 ⇒ y = 8

∴ 8 = 2(b)^1 ⇒ 8 = 2b ⇒ b = 8 ÷ 2 = 4

∴  b = 4

∴ The equation is ⇒ $y = 2(4)^{x}$
