The bear will be at 2^t meters from the starting line “t” seconds after the race begins.

Question

a. Write a function rule (equation) for this situation.

b. Where is the beat at t=5? Write an equation.

c. What time will the bear see their hero if they are 16 meters from the start? Write an equation

Answer 1

distance = 2^t

s(t) = 2^t

s(5) = 2^5 = 32 meters from the starting line after 5 seconds

s(t) = 16 = 2^t

2^t = 16

t= 4 seconds when the bear is 16 meters from the starting line
