What is the vertex form of the equation?

- (x - 6)^2 + 32

Step-by-step explanation:

-x^2 + 12x- 4

= - (x^2 - 12x) - 4

= - [(x - 6)^2 - 36) - 4

= -(x - 6)^2 + 32

f(x) = y

f(-3) = -5

step-by-step explanation:

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
