2. 20 × 43 = 43 × 20
3. 7(4 + 8) = 7 × 4 + 7 × 8
4. 62 = 62
5. If x = y and y = z, then x = z

6. a(bc) = (ab)c
7. 9 × 1 = 9
8. 15 + 0 = 15
9. 2a + b = b +2a

Asap describe the transformations required to obtain the graph of the function f(x) from the graph of the function g(x). f(x)=-5.8sin x. g(x)=sin x. a: vertical stretch by a factor of 5.8, reflection across y-axis. b: vertical stretch by a factor of 5.8,reflection across x-axis. c: horizontal stretch by a factor of 5.8, reflection across x-axis. d: horizontal stretch by a factor of 5.8 reflection across y-axis.
