f(x)=4^x5+8x+2

 

if it is even then

f(x)=g(-x)

and if that happens then it means the graph has the x axis as the axis of symmetry.

Does f(1)=f(-1)   if it doesn't then it is NOT even. If it does then it might be even you will need to think a little.

 

If it is odd then

f(-x)=-f(x)  and it will have 180 degrees rotational symetry about the origin.

does f(-1)= -f(1)  ??

 

You can cheek you answer by graphing it here
