The vertex is
Step-by-step explanation:
For a general quadratic function the form is:
For the function
The values of the coefficients for the function are the following: , ,
Take the value of b and divide it by 2. Then, the result obtained squares it.
Add and subtract
Write the expression of the form

The correct answer is (1,-4))
Take The original point and add/subtract the change. (-1+2, 2-6)
Sector area= theta/360 x πr^2
Radius= 24/2= 12
Sector area= 120/360 x π(12)^2
Final answer :
Sector area = 48π
