The solution to this problem is 0.77. You can find this answer through a math trick that always works. You should subtract the smaller absolute value from the larger absolute value of each number, and then reverse the operation if the larger absolute value is not the one you are subtracting from. In this case, I subtracted .14 from .91, and then made it negative because .91 was had the greater absolute value.

Since we can use direct substitution, we can just plug in x=0 into the equation.

$x^{2} -1$

$=0^{2}-1$

$=-1$

Thus, your answer is the first choice.

Have an awesome day! :)
