Expert Solution

Step 1

First of all, to define a bijection from [a, b] to [c, d], the condition $d - c = b - a$ must be satisfied. Since we are asked to define a bijection between the two sets, we assume that the above condition is satisfied.

Now, we have a bijection which is a strictly monotonic function that sends a from [a, b] to c of [c, d] and b from [a, b] to d of [c, d].
