Tyler says that Figure B is a scaled copy of Figure A because all of the peaks are half as tall.

Do you agree with Tyler?

• No. For the smaller figure to be a scaled copy, the figure would have to be half as wide as well.

• No. For the smaller figure to be a scaled copy, the figure would have to be twice as tall.

• Yes, figure B is a scaled copy of figure A.
