Rational,whole,integer,real
Step-by-step explanation:

Using the point C (-4,-2) and the refection rule:


200 cm is 2 m so 40m/2m = 20. Thus she will have 20 pieces

(a) For dx/dt=6, dy/dt = 2·6 = 12
(b) For dy/dt=2, 2 = 2·dx/dt ⇒ dx/dt = 1

The value of x is irrelevant for this question.
=====
If your function is 2^x +1 or 2^(x +1), it needs to be written as such. The answer above applies to the function given.
