I think the answer is 8.5 ,I’m not sure about this tho
where is the graph????
Step-by-step explanation:
Arcsecant or arcsec or sec⁻¹ is an inverse trigonometric function. And many calculators don't have a key for them because they can be calculated with basic trigonometric functions like so:
sec⁻¹(x)=cos⁻¹(1/x).
So the correct answer is the fourth one: y=cos⁻¹(1/x).
