Question

Create an exponential function that models this situation based on the time in secons in the video.

Answer 1

Answer:

• B(t) = 2*$2^{t}$

Step-by-step explanation:

You have all correct choices.

We can use the given values and work out the equation:

• B(t) = $ab^{t}$
• B(0) = 2 ⇒ a*b⁰ = 2 ⇒ a = 2
• B(1) = 4 ⇒ a*b¹ = 4  ⇒ 2b = 4 ⇒ b = 2

The function for this situation is:

• B(t) = 2*$2^{t}$
