The graph shows the cost of buying concert tickets tell whether x and y are proportional if so find and interpret constant of proportionality then find the cost of 14 tickets

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

final total: 63

step-by-step explanation:

60 times sales tax

60 times 0.05

3

60 + 3

63
