Use the graph of f(t) = 2t + 2 on the interval [–1, 4] to write the function f(x), where f of x equals the integral from 1 to x of f of t dt.
f(x) = x2 + 3x
f(x) = x2 + 2x – 12
f(x) = x2 + 2x – 3
f(x) = x2 + 4x – 8

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
