You have 8 cups of flour. a recipe calls for 2/3cup of flour. another recipe calls for 1/4 cup of flour. how much flour do you have left after making the recipes?

the correct answer is b.

this is because an open circle means < or > & since the line goes left it is < -3.

the next one has a filled circle so it can only be ≥ or ≤ and since the line goes right from 1 it is ≥ 1

hope that

(f+g)(x) = 3^x+10x+4x-2

      =3^x +14x-2

choice b
