F(3) = x2 - 4x
what is the answer to this problem

f(3)=18

Step-by-step explanation:

so 3=x

F(x)= 2x-4x

f(3)=2(3)-4(3) since its -4 you would add

F(3)=6+12

F(3)=18

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.

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
