Which is the graph of f(x) = (x + 3)(x – 2)? on a coordinate plane, a parabola opens up. it goes through (negative 3, 0), has a vertex at (negative 0.75, negative 6), and goes through (2, 0). on a coordinate plane, a parabola opens up. it goes through (negative 2, 0), has a vertex at (0.5, negative 6. 2), and goes through (3, 0). on a coordinate plane, a parabola opens down. it goes through (negative 3, 0), has a vertex at (negative 0.5, 6. 2), and goes through (2, 0). on a coordinate plane, a parabola opens down. it goes through (negative 2, 0), has a vertex at (0.5, 6. 2), and goes through (3, 0).

the answer to question 1 is -8, 28.

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

answer: a parabola

steps:

(x-1)(x+4)   = x(x+4) - 1(x+4) = (x^2 + 4x) - (x+4)

                = x^2 +4x -x -4   = x^2 +3x -4

which is a parabola
