Full solution stays hidden until you ask for it.
1. Inside multipliers affect input values inversely.
2. f(kx) compresses horizontally by 1/k when k > 1 and stretches when 0 < k < 1.
3. f(-x) reflects across the y-axis.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Vertical scale interpretation.
