Question

Liam says that the graph of the function between x=1 and x=3 is non linear and increasing . What error could he have made in analyzing the graph ?
A) he did not make an error

B) he mistakenly identified this interval as increasing

C) he was looking at the interval between between x= 3 and x=4

D) he was looking at the interval between x= 4 and x= 6

Answer 1

I would say that (d) is the correct answer because the section between x=4 and x=6 is not linear but exponential but it is still increasing. The section between x=1 and x=3 however is linear and therefore his answer is incorrect.
