I would say that (d) is the correct answer because the section between x=4 and x=6 is not linear but exponential but it is still increasing. The section between x=1 and x=3 however is linear and therefore his answer is incorrect.
Answer: 1,833,615
Step-by-step explanation:
Hi, to answer this question we have to apply an exponential growth function:
A = P (1 + r) t
Where:
p = original population
r = growing rate (decimal form)
t= years
A = population after t years
Replacing with the values given:
A = 800,000 (1+ 5/100)^17
A = 1,833,615
Feel free to ask for more if needed or if you did not understand something.
Step 1
(((((3•(a2))•b)+5ab)-4ab)+(a•(b2)))+(23a2•b)
step 2
((((3a2 • b) + 5ab) - 4ab) + ab2) + 23a2b
step 3
Pull out like factors :
11a2b + ab2 + ab = ab • (11a + b + 1)
step 4:ans
ab • (11a + b + 1)
