Draw a sketch of the graph of the equation $\displaystyle {y}=\sqrt{{{x}-{1}}}$, on a piece of paper. Then answer the following questions. Note: For the intercepts, write the answer as an ordered pair or a list of ordered pairs separated by commas. If an intercept does not exist, enter $\displaystyle {D}{N}{E}$. Round your answer to three decimal places as needed.

Horizontal-intercepts:

Vertical-intercept:

Is the graph symmetric with respect to the horizontal-axis? ? no yes

Is the graph symmetric with respect to the vertical-axis? ? no yes

Is the graph symmetric with respect to the origin?? no yes
