Hi Kiara
2x²+28x+96
First thing you need to find the common factor
So the common factor is 2
2(x+6)(x+8)
I hope that's help:0
Why 2 is the common factor ?
Because we were looking for a number that can divide all of them at the same time without decimal, so that's why :)
Answer:469 million
Step-by-step explanation:
Given
The population of a country at t=1900 is 420 million
and P'(t) is a constant therefore P(t) is a linear function of time
assuming P(t)=7t +c
at t=0 i.e. 1900 at starting Point P(t)=420 million
i.e.


Thus 

Thus at 1907 Population is 469 million
P'(t)=7 indicates that growth rate of Population is constant equals to 7 billion
i)
Axis of symmetry:
x = - 2 (the value of x vertex)
ii)
Vertex:
The vertex of a parabola is the point where the parabola crosses its axis of symmetry.
The vertex (-2, -4)
iii)
Domain:
All real number
iv)
Range: y >= - 4 (the vertex is the lowest point on the graph, it has minimum value and opens up)
