The quadratic function in vertex form is:
y = a(x - h)^2 + k
Where:
vertex = (h, k)
Axis of symmetry: x = h
The value of “a” determines whether the graph opens up or down, and makes the parent function wider or narrower.
The value of “h” determines how far left or right the parent function is translated.
The value of “k” determines how far up or down the parent function is translated.
Now that we have these definitions, we can substitute the given values into the vertex form to solve for “a”:
Use vertex = (-4, -1) and y-intercept, (0, 7):
7 = a(0+ 4)^2 - 1
7 = a(4)^2 - 1
7 = a(16) - 1
Add 1 to both sides:
7 + 1 = a(16) - 1 + 1
8 = 16a
Divide both sides by 16 to solve for “a”:
8/16 = 16a/16
1/2 = a
Since a = 1/2 (which is positive, implying that the parabola opens upward), and the vertex occurs at point (-4, -1) as the minimum point:
The quadratic equation in vertex form is:
y = 1/2(x + 4)^2 - 1

Answer:
Therefore, the coordinates of point 'b' would be (-0.5 , 4.75).
Step-by-step explanation:
We have been given that point a is at (-2,4) and point c is at (4,7) .
We are asked to find the coordinates of point b on segment ac such that the ratio is 1:3.
We will use section formula to solve our given problem.
When point P divides a segment internally in the ratio m:n, the coordinates of point P would be:
Therefore, the coordinates of point 'b' would be (-0.5 , 4.75).
Answer:
Probability of getting {THT} is 0.125
Step-by-step explanation:
Since 3 fair coins are tossed we can get the sample space for the experiment.
Sample space of the experiment = {HHH, HHT, HTT, HTH, TTH, THH, THT, TTT}
As per question ,
Getting Tail , Head, Tail is a success so all other events other than {THT} is a failure.
Therefore probability of getting {THT} = = 0.125
