Which function has an inverse that is also a function? {(-1, -2), (0, 4), (1,3), (5, 14), (7,4)} {(-1,2), (0, 4), (1,5), (5, 4), (7, 2)} {(-1, 3), (0, 4), (1, 14), (5, 6), (7, 2)} {(-1, 4), (0, 4), (1, 2), (5,3), (7, 1);

step-by-step explanation:

so first find out how much each is worth.

quarter= 25 cents

dime= 10 cents

pennies= 1 cent

then multiply each by how much each is worth.

200                     150                   300

x                         x                     x   1

  25                       10              

                                  300

1000                     1500

+                          

4000                                      

5000                                  

then count 2 from the back and add a period.

$50.00
