Answer
See below.
Work Step by Step
If we plug in the respective $x$ and $y$ values of $(x,y)$, we can check if it satisfies the equation, if it does, it is on the graph, if it doesn't it is not on the graph.
Hence here: $(0,0)\rightarrow0^4-\sqrt0=0-0=0$, so it is on the graph
$(1,1)\rightarrow1^4-\sqrt1=1-1=0\ne1$, so it is not on the graph
$(2,4)\rightarrow2^4-\sqrt4=16-2=14\ne4$, so it not is on the graph
