The function \( h(p) \) represents the cost for a company to manufacture \( p \) posters. What is the domain of the function? all integers all real numbers all non-negative integers allive rational numbers

Determine the domain and the range of the relation, and tell whether the relation is a function. \( \{(2,7),(18,-10),(34,7),(2,9),(59,9)\} \) The domain is \( \{\square\} \). (Use a comma to separate answers as needed. Type each answer only once.)

11) \( \left((-3)^{2}\right)^{-2}= \) a) 81 b) \( \frac{1}{81} \) c) -81 d) \( \frac{1}{-81} \)
