Find the missing value to make the point (3, __) on the equation y = 7x^2 + 9

Answer 1

To find the missing value, we need to substitute x = 3 into the equation.

y = 7(3)^2 + 9
y = 7(9) + 9
y = 63 + 9
y = 72

Therefore, the missing value is 72. So, the point is (3, 72) on the equation y = 7x^2 + 9.
