A linear function refers to a kind of function that is used to depict a straight line on the coordinate plane. The value of f(4) = 7
It is to be noted that the value of x in relation to their frequencies are indicated in the table.
Given f(x), the value of f(4) as traceable from the table = 7
Thus F(4) = 7.
It is to be noted that linear function have a graph that possesses a straight line; or a polynomial function whose degree is either one or zero.
