The function f(x) = 2x/3 is an example of a rational function.

a. true

b. false

A. True

Step-by-step explanation:

The function F(x) = 2x/ 3 is a rational function since the numerator, 2x, is a polynomial and the denominator 3, is also a polynomial (a constant is still a polynomial ).

step-by-step explanation:

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
