What is the x-coordinate of the vertex of the parabola whose equation is y = 3x^2 + 12x + 5?

x = -4
x = -3
x = -2

answer: 19 is   2

step-by-step explanation: i just looked at your answer and wrote it down

we have the parent function given by,

1. the function is translated 5 units to the left.

so, we get,   becomes

2. the function is translated 5 units to the right.

so, we get,   becomes

3. the function is translated 5 units upwards.

so, we get,   becomes

4. the function is translated 5 units downwards.

so, we get,   becomes

5. the function is reflected across x-axis.

so, we get,   becomes

6. the function is reflected across y-axis.

so, we get,   becomes .
