![## Initial Value Problems and Solutions
**Problem 3:** For each of the following initial value problems, write down a formula for the solution \( x(t) \) and determine its maximal interval of existence.
### (a)
\[ \dot{x} = x^2 - 4 \quad \text{with} \quad x(0) = 0 \]
### (b)
\[ \dot{x}_1 = x_1^2, \quad \dot{x}_2 = x_2 + x_1^{-1} \quad \text{with} \quad x_1(0) = 1, \quad x_2(0) = 1 \]
In this problem, the objective is to find solutions \( x(t) \) based on the given initial conditions and determine the interval over which these solutions are valid.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1d3efa04-e257-4d52-b2ca-75c754647d81%2Fcce6028c-d841-40b0-afdb-241e3db5b59d%2Fqiyhzrj_processed.png&w=3840&q=75)
