Find the missing value to make the point (5, __) on the equation y=−9x^2+ 4.

Answer 1

To find the y-value when x=5, we substitute 5 for x in the equation y = -9x^2 + 4:

y = -9(5)^2 + 4
y = -9(25) + 4
y = -225 + 4
y = -221

Therefore, the missing value to make the point (5, -221) on the equation y = -9x^2 + 4.
