Answer:
The answer is f(x) = 0.8(2^x)
Step-by-step explanation:
∵ f(x) = 0.8(2^x)
∵ x = -2 ⇒ ∴ f(-2) = 0.8(2^(-2)) = 0.2
∵ x = -1 ⇒ ∴ f(-1) = 0.8(2^(-1)) = 0.4
∵ x = 0 ⇒ ∴ f(0) = 0.8(2^(0)) = 0.8
∵ x = 1 ⇒ ∴ f(1) = 0.8(2^(1)) = 1.6
∵ x = 2 ⇒ ∴ f(2) = 0.8(2^(2)) = 3.2
∴ The answer is f(x) = 0.8(2^x) ⇒ The fourth answer
Answer:
10
Step-by-step explanation:
(85^4 - 75^4)/(85^3 + 85*75^2 + 75*85^2 + 75^3)=10
