To Find :
The equation of the quadratic whose Vertex is at ( −4,−5) and passes through the point (−3, −7).
Solution :
A quadratic equation in vertex form is given by :
( Here, h, k is the vertex )
y = a(x-(-4))² + (-5)
y = a(x+4)² - 5
Now, putting (-3,-7) in above equation:
-7 = a( -3 + 4 )² - 5
a(1)² = -2
a = -2
Therefore, the equation of the quadratic is y = -2(x+4)² - 5 .

Step-by-step explanation:
Answer:
Domain f(x) = R - {1}
As it is a rational expression, the denominator cannot be zero.
Now the function holds all real values except 1 for which the denominator will become zero which is undefined.
Therefore the domain will be all real numbers except 1.
Answer:
Step-by-step explanation:
m∠ QPO + (x + 16)° + (6x − 4)° = 360°
m∠ QPO = (x + 16)° + (6x − 4)°
m∠ QPO + (2x + 16)° = 180°
m∠ QPO = (6x − 4)° + (2x + 16)°
