Answer:
(x, y) = (-20, 7), (-5, -2), (0, 3), (15, -4), (30, 5)
Step-by-step explanation:
You want 1/5x to match the x-value in the given table. To make that happen, multiply the given x by 5.
Example: when (1/5x) = -4, f(1/5x) = 7, so x = -4·5 = -20 for y = 7.
The transformation f(1/5x) is a horizontal expansion by a factor of 5, so each point of f(x) is now 5 times farther from the y-axis than it was.
