How to show that a Function is One-to-One algebraically | SHS 1 ELECTIVE MATH

This video discusses how to prove whether a function is one-to-one. A one to one function is the one where if the elements in the domain have distinct values in the codomain or range. For a function to be one to one, f(a) = f(b) such that a = b.

[mosesmuhane]

no hitting around, boss you went direct on point .

[kilikhontrol]

Yoo thanks bro 😊 for the explanation 7:26
That was the exact thing I was looking for

[malogna]

I need a bit of clarification. For the first example, shouldn't the restriction be X not equal to -2 .

4:50 why not also cancel sqrt of b with square that would give a = b hence one to one?

Watching from the Philippines, for GenMath

Is the function f(x)=x/y from z to z : one to one, onto or both ?
I do believe that it is not even a function, but the choices for this question in my exam didn’t even include this option.

[Eikenv]

Keep up the good work!
Was very clear to understand.

[Birrby]

5:17 why can’t we cancel both square roots so they’re both equal to +-A and +-B why cancel A only is there anything specific?

[obedpksomuah]

I just love this wooww.... I never knew root of b was + or - b.... Appreciation!

[NawaYT]
