At the grocery store, bananas were on sale at 4 for $0.39. If Pierre and his mother bought 18 bananas, about how much did they spend?

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

r and t.

both are 64 degrees.

the answer is y = 11.54

hope this : )
