Class A has 13 pupils and class B has 29 pupils. Both classes sit the same maths test.
The mean score for class A is 31.
The mean score for class B is 61.

Ineed show the photo because i need more information

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

there is a hike in both the graphs so the graphs are increasing on their domain.x-intercept of log x and log 6x are differentthere is a vertical asymptote of both the graphs so there is no y-interceptas both the graphs are increasing so there is no horizontal asymptote

4x 20 is 80 but if ther machine is broken then there is none you have to redo the test
