Which statement describes what's happening correctly?
ANSWER:
[a] For each additional game played, the cost increases by $10.
QUESTION:
What will the function f(x) = x² look like translated 3 units right and 8 units down?
ANSWER:
To move up or down just add or subtract the constant equal to the units moved.
So, just to move it 8 units down, would give us
g(x) = x² - 8
Now, To move horizontally replace each x with (x ± c).
- If you move it to the right, you need x - c
- If you move it to the left , you need x + c
So , since we are moving 3 units to the right, we replace the x with x - 3.
g(x) = (x - 3)² - 8.
