Answer:
(-0.75, -0.25)
Step-by-step explanation:
<h3>Example
</h3>
Question:
Determine the coordinates of the vertex for the given parabola equation: y= 3x2+12x -12
Solution:
Given equation: y= 3x2+12x -12
Here a = 3, b = 12
We know that the formula to find the x- coordinate is given by -b/2a
= -12/2(3)
= -2.
Therefore, x -coordinate is -2
Now, substitute the value of x in the given equation, we get y= -24
Hence, the vertex coordinates (h, k) is (-2, -24)
