Milo's worksheet shows the row (4, 2) of y = √x. g(x) = √(x + 5). Which row of g does it move to?
In a notebook, Noah moves the point (8, 2) of y = ∛x to the graph of g(x) = ∛x − 6. Where does it land?
Pia marks (3, 8) on y = 2ˣ in pencil. The graph moves to g(x) = 2^(x − 4). Where is the point now?
In a notebook, Zee graphs y = 2ˣ and then g(x) = 2^(3x). Which move turns one into the other?
- Horizontal shrink by a factor of 1/3
- Left 3
- Horizontal stretch by a factor of 3
- Vertical stretch by a factor of 3
Ari sketches y = log₂x in pencil, then g(x) = (1/2)log₂x. How does the graph change?
- Right 1/2
- Vertical shrink by a factor of 1/2
- Up 1/2
- Horizontal shrink by a factor of 1/2
On a puzzle card, Bo sees y = 2ˣ and g(x) = 2^(x/2). Which move is it?
- Horizontal stretch by a factor of 2
- Left 1/2
- Horizontal shrink by a factor of 1/2
- Vertical shrink by a factor of 1/2
On a worksheet, y = √x has the row (9, 3). Esme writes the table of g(x) = 4√x. What is g(9)?
In a notebook, Jun has the row (3, 8) of y = 2ˣ. g(x) = 2 · 2ˣ. What is g(3)?
Kira works in pencil: the parent y = log₂x has the row (16, 4), and g(x) = 5 log₂x. What is g(16)?
On a puzzle card, (2, 1/2) is a row of y = 1/x. Luz needs g(2) for g(x) = 6/x. What is it?
