The formula for a quadratic function is y=ax^2+bx+c.
The vertex is h, k. This can be found by evaluating y to get k, and dividung -b by a in order to get h.

Hope this helps!

Answer:Parabolas always have a lowest point. This point, where the parabola changes direction, is called the "vertex". If the quadratic is written in the form y = a(x – h)2 + k, then the vertex is the point (h, k).

Please help Maggie's brother is 3 years younger than twice her age. The sum of their ages is 30.
denpristay [2]
I’m not sure if this is correct but this is the way i would solve it.

first, make an equation with the given information

2x-3=30

Then, add three to both sides

2x=33

Finally, divide both sides by 2

x= 16.5


x represents the age of maggie so all you have to do is plug the solution into the equation to check your answer.

2(16.5)-3= 30
