7. Let f and g be functions with domain R and define the function h by h(x) = [f(x) if x>0 9(x) if x ≤0 For each of the following, give an example of ƒ and g such that h has the desired property or explain, why no such example exists. You should give ƒ and g explicitly in math expressions. (a) h is continuous at 0 but not differentiable at 0. (b) h'(0) exists and h" (0) does not exist. (c) h" (0) exists and h'(0) does not exist.

Question

May I ask for a handwritten answer/non-AI generated answer for this question since I really need a well-rounded explanation? Thank you!

7. Let f and g be functions with domain R and define the function h by
h(x) =
[f(x) if x>0
9(x) if x ≤0
For each of the following, give an example of ƒ and g such that h has the desired property or explain,
why no such example exists. You should give ƒ and g explicitly in math expressions.
(a)
h is continuous at 0 but not differentiable at 0.
(b)
h'(0) exists and h" (0) does not exist.
(c)
h" (0) exists and h'(0) does not exist.
