What is the value of y when x = 3 in the equation y = 3x2 + 4x - 7?

-4
-1
4
8

The correct answer is: 4

When x = 3, the equation becomes y = 3(3)^2 + 4(3) -7 = 9 + 12 - 7 = 21 - 7 = 14. Therefore, the value of y when x = 3 is 14. The other options are incorrect as they do not reflect the correct application of the equation they either omit the squared term or do not take into account the values of each term in the equation when x = 3. For example, if we use A: -4, the equation becomes y = 3(3)^2 + 4(3) -7 = 9 + 12 - 7 = 21 - 7 = -3, which is incorrect. Similarly, using B: -1 would result in y = 3(3)^
