Answer:
B is the answer, The graph touches the x axis at x = 0 and crosses the x axis at x = 5 and x = –2.
Step-by-step explanation:
Answer:
(B) 
Step-by-step explanation:
we can use formula

where
Po is the initial population
r is the growth rate
t is the time in months
We are given
initial population of insects
so, Po=6
The scientists find that the insect population, x, is growing exponentially 20% per month
so, r=0.20
now, we can plug these values

there to be a population of 477 insects
so, P(t)=477
now, we plug it
and we get

The answer is x=-7 you just have to cancel the like factors out n you don’t have to divide nothing in this equation.
Answer:
First i found out the gradient then used the equation of a straight line formula to find the tangent
