Question

which of following function are onto funtion if r->r (a) f(x) = 115x 49 (b) f(x) = |x|

Answer 1

Answer:

Hola‼...........❤✌

onto function which codomain=range

(1) f(x)=115x^49

this function range€R

also given codomain €R

hence this is an onto function.

(2) f(x)=|x|

this function range€[0,infinity)

but codomain€R

so, this is not into function.

Hope it's helpful....... ☺
