Q. Does (0,9) make the equation y=−8x2−9 true?Choices:(A) yes(B) no
Substitute x-value: Step 1: Substitute the x-value from the point (0,9) into the equation y=–8x2−9.Calculation: y=–8(0)2−9=–8(0)−9=0−9=−9.
Compare y-values: Step 2: Compare the calculated y-value with the y-value from the point (0,9).Calculation: The calculated y-value is −9, but the y-value from the point is 9.
