Q.Find the possible domains for which the following are one to one functions
a) y = x^2
b) y= x(x-2)
c) y = 2x-3
i kno the for a 1-1 function there is max and min of the 1 y-value for every x-value and vice-versa
all i need is now are the answers and the explanations to the answers.
for eg i for b) i know that domain: x<=0 or x>=1 but why not x<=0 or x>=2
i am so damn confused, please help me thank you
