Answer

no $x$-intercepts; b.

Work Step by Step

Solve by completing the square and then finding two $x$-values that equal the third term when multiplied and add up to the coefficient of the second term. $x^2-2x+2$ $x^2-2x+1=-1$ $(x-1)^2=-1$ The graph has no $x$-intercepts because solving for $x$ results in an imaginary number. When graphing, we see that the equation matches graph b.
