What is the domain indicated on the graph for each
portion of the piecewise function?
1-2, Domain 1st piece
2x + 1, Domain 2nd piece
Domain 3rd piece
f(x) =
X
1st piece:
2nd piece:
3rd piece:

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

what is the original number? you forgot to add it.

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
