I need help on this pls

Step-by-step explanation:

a). Given function is y =

At x = -3,

y =

y = -13.5 + 6 + 1

y = -6.5

For x = -2,

y =

y = -4 + 4 + 1

y = 1

For x = 2

y =

y = 4 - 4 + 1

y = 1

Therefore, table for the given function will be,

x       -3       -2       -1        0        1         2

y     -6.5       1      2.5      1       -0.5     1  

b). From the table given in part (a) we find the points lying on the graph are (-2, 1), (-1, 2.5) and (2, 1).

    These points justify the graph (C)

Therefore, graph (C) will be the answer.

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

after simplifying it i got: -36.25 as my answer. hope that !
