p(x)= √2x^2+9x-18

Is the problem \(\displaystyle \sqrt{2x^2+9x-18}~?\) You wrote \(\displaystyle \sqrt{2}x^2+9x-18\)p(x)= √2x^2+9x-18

You have included within your post no instructions for this exercise, and subject lines frequently don't relate, so I hesitate to assume. Are you maybe supposed to find the domain of the function? If so, then think about the values which you can not have inside a square root. The domain would be all other x-values.p(x)= √2x^2+9x-18

Learn to use grouping symbols.
What types of numbers are NOT allowed inside square roots? What x-values would give you that sort of number? The domain will be everything else.Yes, your version is correct. I just wanted to know the first step because I can't seem to recall it.
All the instructions say is to write the domain of the function in interval notation.
