Does the relation {(5,-2), (5,-8), (4,-6), (7,-1)} represent a function?

Please help

the 4th choice is the correct one

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

r = 78539458390583095803458309458039485093485 or just 3
