Question

How do you find the domain and range of `f(x)=3x^4-10`?

Answer 1

Domain: `x in RR or (-oo,oo)`
Range : `f(x)>= -10 or [-10,oo)`

Explanation:

`f(x)= 3 x^4-10`

Domain : Possible input value of `x` . Any input of `x` is possible.

Domain: `x in RR or (-oo,oo)`

Range : Possible output value of `f(x) ; x^4>=0` .

Range : `f(x)>= -10 or [-10,oo)`
