Find the missing value to make the point (5, __) on the equation y=−5x^2+11

Question

y=__

Answer 1

Using the equation y = -5x^2 + 11, plug in x=5 to find y:

y = -5(5)^2 + 11
y = -5(25) + 11
y = -125 + 11
y = -114

Therefore, the missing value to make the point (5, -114) on the equation y = -5x^2 + 11.
