Question

F(x) = |2x - 3|

check if the function is one one and onto
give full solution please​

Answer 1

Answer:

A function is said to be onto if there exist an x for every y.

Hence to prove a function to be onto just solve the function for an x.

Eg: f(x) = 3x + 5.

Let f(x) = y = 3x + 5.

x= (y-5)/3.

Hence there exist a x for every y.

And hence the function is onto.

Answer 2

Step-by-step explanation:

here's the answer along with the solution

thr function f(x) is neither one-one nor onto
