i.e. 
Thus, the standard form of the product
is
.
" the sum " means add
16 + x = 20 <= ur equation
x = 20 - 16
x = 4 <== the number
Answer:
Step-by-step explanation:
Solve for x=0 and x=1
y(0)=2(3^0)=2(1)=2 so (0,2) is a point.
y(1)=2(3^1)=2(3)=6 so (1,6) is a point.
Only graph B has those two points.
