Graph B represents the linear function.
Given that,
4 curves on 4 individual graphs are shown,
Graph that has linear function is to be determined.
What are functions?
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
The function in the graph A, C, and D are parabolic, periodic, and cubic polynomial recpectively. And function in graph B shows the linear function because it is a straight line.
Thus, Graph B represents the linear function.
