Please answer ASAP, need to know.

Step-by-step explanation:

Since, the function given in the graph is a piecewise function,

Piece 1 is defined in the domain → -9 ≤ x ≤ -3

Piece 2 is defined in the domain → -3 < x ≤ 4

Piece 3 defined in the domain → 4 < x < 9

x = -3.0001 is lying on piece 1,

f(-3.0001) = 3

x = 3.999 is lying on piece 2,

f(3.999) = 7

x = 4.0001 is lying on piece 3,

f(4.0001) = -3

x = 9 doesn't represent any piece,

f(9) = Undefined

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
