Question

Function f(x) = $x^{56}$ + $x^{14}$ + 1 defined on f: R $\to$ R is one – one function.

• A. True
• B. False

Answer 1

The correct option is B

False

The given function is an even function as we replace x by –x the function will not change. And we know that all the even functions are many one functions as x and –x will give the same value. For example, here if we put -2, and 2, we’ll get the same output.
