What is the domain of the discrete function shown below? G(x) = {(4, 12), (5, 15), (6, 18), (7,21)}

c

step-by-step explanation:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

the correct answer is c

(1,-1) i hope this
