Answer:
{(x, 4f(x)) = (-2,0), (3, 16), (7, 48), (9, -52)}
Step-by-step explanation:
We have the following set of ordered pairs:
(x, f(x))
(-2,0). So f(-2) = 0. That is when x = -2, y = 0.
(3,4). So f(3) = 4. That is, when x = 3, y = 4.
(7,12). So f(7) = 12. That is, when x = 7, y = 12.
(9, -13). So f(9) = -13. That is when x = 9, y = -13.
find the set of ordered pairs (x, 4[f(x)]).
We just need to multiply the values of y by 4. So the set is
{(x, 4f(x)) = (-2,0), (3, 16), (7, 48), (9, -52)}
