What is the equation, in vertex form, of the quadratic function that has a vertex at V(-2,-6) and passes through point P(-4, - 7)? (7 points) O y = f(x + 2)2 - 6
O y = - 4(x + 2)2 + 6
Oy=-(+ 2)2 - 6
Oy - - (1 - 2)2 – 6

a. the residual plot for model 1 has a random pattern and is a good fit for the data.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)  

well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.
