Question 465821: 1) f(x)= sqrt of 5-x Determine the domain and graph
I converted it to f(x)= sqrt -x+5 I have a domain of (-00,5] so I graphed it 5 on the x to -00 teacher stated it was wrong but did not state what was wrong.
2) f(x)= -2/x^+2x-3 determine the domain and graph I had a domain of (-00,-3)U(-3,00) he says that was wrong I graphed it correctly he said
Thanks for your assistance
