anonymous one year ago If the range of the function f(x)=x4 is {28, 30, 32, 34, 36}, what is its domain?

in a function, just remember that domain is all the x values and range is all the y values. the function can be written as y=x^4 yo have all the y values, you can calculate all the x values (domain) so$x=\sqrt[4]{y}$

Use the formula Niti gave you and substitute the values accordingly and see what you get for your first pair of y-coordinates.
