Answer:
(a) 3
(b) 3
(c) 3
(d) 3
Explanation:
(a) lim p(x) = ?
s--->-2⁻
As s tends to -2 from the left, the curve p(s) becomes 3
lim p(x) = 3
s--->-2⁻
(b) lim p(x) = ?
s--->-2⁺
As s tends to -2 from the right, the curve p(s) becomes 3
(c) lim p(x) = ?
s--->-2
As s tends to -2, the curve p(s) becomes 3
(d) p(-2) means the y value when x = -2, which 3 from the graph
