With these three. im not getting it.
given the function f: [−π4 ,π4 ]→[−1,1]; f(x)=sinx f: [−π4,π4]→[−1,1]; f(x)=sin⁡x , check which one(s) of the properties it has.
given the function f: [−π4 ,π4 ]→[−12 √ ,12 √ ]; f(x)=sinx f: [−π4,π4]→[−12,12]; f(x)=sin⁡x , check which one(s) of the properties it has.
