Question

F(x)=2x^3-5 is this a one to one function

Answer 1

Answer:

$\boxed{\boxed{\pink{\sf Yes \ it\ is \ one\ to \ one \ function .}}}$

Step-by-step explanation:

A function is said to be be one-to-one ( injective) if every y-value has only one corresponding x-value. The given function is ,

$\bf \implies f(x) = 2x^3-5\\\\\bf\implies y = 2x^3-5$

Here I have made the graph of " Desoms Graphing calculator. "

Now ,on plotting its graph we see that every y-value has only one corresponding x-value . Hence , ihe given function is a injective function that is one to one function.

Hence the given function is one to one ( injective ) function.
