Which characteristic is correct for the function f(x)=4^x5+8x+2
neither even nor odd
both even and odd
if it is even then
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
