The graph is stretch/shrunk by a factor of a. The Domain is h=
The wood is 10 inches and you're cutting it into 1/2 pieces, so divide 10 by 1/2, which is 20, The carpenter can cut 20 dowels.
Since it's a reflection over the x axis, the x coordinates will stay the same while the y coordinates will be opposite of what they are.
After reflected: A'(-2,-3), B'(0,-3), C'(-1,1)
0.06 is 10 times 0.006; 0.06 = 10 * 0.006
You can find this by solving 0.06/10 = 0.006
You should graph it first then post
