Q. Is (−2,−3) a solution to the equation y=x2+−1?Choices:(A)yes(B)no
Substitute and Calculate: To check if the point (−2,−3) is a solution, substitute x=−2 and y=−3 into the equation y=x2−1.Calculation: y=(−2)2−1=4−1=3.
Compare Values: Compare the calculated y-value with the y-coordinate of the point.Calculated y=3, Point's y-coordinate =−3.Since 3=−3, the point (−2,−3) is not a solution to the equation.
