1 The increase in the length of an ivy plant,in metres, is modelled by the equation
f(x) = 2(1.1)*, where x is the time in weeks.
a Find the initial length of the ivy plant.
b Find the length after 10 weeks.
c Find how long it takes for the plant to
reach a length of 10 metres.
+37158 f(x) = 2(1.1)*, where x is the time in weeks. something is missing in your equation....
f(x) = 2 + (1.1)*x Perhaps?
initially x = 0 and the ivy is 2 mt tall
2+ 1.1 x when x = 10 is 13 m
c,) 10m = 2 + 1.1 x x = 8.2 weeks
