    i think of it this way sum of 2(i)^0 from i=-1 to 4 = 2(-1)^0+ 2(0)^0+2(1)^0+2(2)^0+2(3)^0+2(4)^0 = 12 if you know something about arithmetic series it should help

    i know but that 0^0 is confusing me because it is undefined

    0^0 is indeterminate this is tricky here

    does that help? We are taking the sum of the y values for f[n]=n. at f[-1]+f[0]+...+f[4] a way of visualizing functions might help

    but we have f(n)=2 omg omg ok so we f(-1)+f(0)+f(1)+... =2+2+2+ omg you are my hero
