need help with two questions please
What is the domain of the function v=−6r2 if the range is v≤0?


For the function f(x)=x3, if the domain of x is R, what is the range of f(x)?


Sagot :

Answer:

v is negative for every x, meaning the domain is all values in R, whatever goes under the squared sign will come out as positive and the left out -ve sign will make V negative for all x in R

range of f(x) is -inf to +inf

Step-by-step explanation:

the cubic power doesnt affect the sign
