One-to-One Property
Remember that a relation is a function if every input corresponds to exactly 1 output.
If every output also corresponds to exactly 1 input, then we say the function is one-to-one.
One-to-one functions will pass the horizontal line test.
Exponential functions are one-to-one. We can use this property to solve for x.
