SOLUTION: I need to find the domain and range of T(t)= 2t^4 + t^2 - 1 . Do I add the 2t^4 + t^2 first? 3t^6 -1? I'm still very unclear about finding domain and range. Thank you for your h

Question 457569: I need to find the domain and range of T(t)= 2t^4 + t^2 - 1 . Do I add the 2t^4 + t^2 first? 3t^6 -1? I'm still very unclear about finding domain and range.
Thank you for your help

You can put this solution on YOUR website!
find the domain and range of T(t)= 2t^4 + t^2 - 1
.
"Range" specifies the possible values of T(t)
.
"Domain" specifies the possible values that t can take.
In this case, the domain is "all real numbers" or int can be specified as:
(-oo, +oo)
where oo is infinity
.
Sometimes the expression (not in your case) has t under a radical (now you don't want t to drive it negative) OR if it has the t in a denominator (now you don't want t to drive it to zero).
