I had to do this question :
The function f is defined for the domain -3≤ x ≤3
Find the range of f
I know we're not supposed to just copy questions we are supposed to do but I tried this and I kept getting the answer 53 ≤ x ≤ 89 which is apparently wrong
what I did was insert -3 into the function first and get 89 as one end of the domain and then insert 3 into the function and get 53 and I just rotated them around from
89 ≤ x ≤ 53
to
53 ≤ x ≤ 89
anyway, that's not the answer I'm supposed to get
can anyone help? Thanks
