Question

find the range of this function

Answer 1

Answer:

Step-by-step explanation:

let t = x^2+1/x^2+2

1-1/x^2+2

min value of above is 1/2

so range of t is [1/2 , infinity )

if you look in the graph of sin^- x

take only the graph which is covering range of t values

so option b is correct
