Question

guys plz answer this step by step its urgent ​

Answer 1

Answer:

Step-by-step explanation:

1. Domain and range of inverse cosine function. The domain for Cos–1 x, or Arccos x, is from –1 to 1, just like the inverse sine function. So the x (or input) values. The range for Cos–1 x consists of all angles from 0 to 180 degrees or, in radians, then you write these expressions as.

function f is real only when sin3x is not equal to 2.

so domain of f =R.

by solving.....

Range= 1/3 and 1
