A twice-differentiable function g satisfies
g′(x)=pepx+q,
where p and q are real constants. Additional information is provided:
* g(0)=2.
* g(1)=e+2.
* The inverse function g−1 exists in a neighborhood of x=0, and (g−1)′(2)=21.
Respond to each part, giving full justification.
a. Express g(x) in terms of p, q, and an integration constant, and then use g(0)=2 to determine that constant.
b. Using g(1)=e+2, write an equation relating p and q.
c. Using (g−1)′(2)=21, write a second independent equation relating p and q.
d. Solve the system of equations obtained in parts (b) and (c) to find the exact values of p and q. Explain how you know your solution is unique.
