Help me. Please check if I did the domain range and graph right. Thanks.

1. Everything is correct except your graph.

2. The range is $\mathbf{R}\backslash \{6 \}$.

1. Could you show me how to graph it. Thanks.

2. Oh, does that mean my graph is also wrong?

1. The line should end at $x = 1$ with a QUADRATIC graph starting at $x = 1$.

2. The graph is almost right, you just need a hole at $(3, 6)$ on the line.

1. Sorry to bother but can you draw it? I cant seem to picture it out. Im really not good at this sorry.

2. I get it. Ty! Oh. Is the range = [6] or not equal to 6?

$\mathbf{R}\backslash \{6\}$ means all the real numbers except 6.

For the graph, draw the graph of $y = x^2$. Then get rid of everything to the left of $x = 1$.
