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.

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
