Is the following graph planar? If not why? If yes draw a planar configuration . its planar because when we stretch it out the edges don't cross over .. hers's my attempt ..... Looks like a knights head....Is this ok ?

No, you free a different graph. Check the degree of the vertex that has the loop.
Try moving the very center vertex to the upper right corner.
It's not planar. K₅ is sitting in that graph (after removing some edges and vertices).
Thanks all..I'll work on these ..
