Answer:
(1, 0 )
Step-by-step explanation:
using the rule of logarithms
x = n ⇒ x =
, then
y = (x + 2) - 1
to find the zero let y = 0 , that is
(x + 2) - 1 = 0 ( add 1 to both sides )
(x + 2) = 1 , then
x + 2 = = 3 ( subtract 2 from both sides )
x = 1
the zero is (1, 0 )
Let
x--------> the time in hours
y-------> the distance in miles
