The amount you spend at the fair can be represented by the function: y=2x+10

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.
