Describe the transformations that took place from f(x) to g(x):
g(x)= -f(2x)

A reflection in the x-axis and a vertical stretch by a factor of ½.

Step-by-step explanation:

The parent function is f(x).

The transformed function is

The negative sign means a reflection in the x-axis.

The 2 multiplying inside means a horizontal stretch by a factor of

Therefore the transformation, is a reflection in the x-axis and a vertical stretch by a factor of ½.

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
