Function and graph
Showing that the Function ( f(x) = 3x - 2 ) is One-to-One
1. Algebraic Method
To test if a funct
ion is one-to-one, we assume:
Since the only solution is ( x_1 = x_2 ), the function is one-to-one.
Cubic Function
Reciprocal function ( rational)
Square Root function
Exponential graph
Absolute Value
