Question
If 2 + 8 = 16 x , what is the value of x + 4 ?
The correct answer is: 8
HINT – Find the value of x
SOLUTION – Let F(x) = x + 4
It is given that 2x + 8 = 16
2x = 16 – 8
2x = 8
x = 4
Now, substituting the value x = 4 in F(x)
We get, F(4) = 8
Hence our answer is 8

A shipping service restricts the dimensions of the boxes it will ship for a certain type of service. The restriction states that for boxes shaped like rectangular prisms, the sum of the perimeter of the base of the box and the height of the box cannot exceed 130 inches. The perimeter of the base is determined using the width and length of the box. If a box has a height of 60 inches and its length is 2.5 times the width, which inequality shows the allowable width x, in inches, of the box?

There were no jackrabbits in Australia before 1788 when 24 jackrabbits were introduced. By 1920, the population of jackrabbits had reached 10 billion. If the population had grown exponentially, this would correspond to a 16.2% increase, on average, in population each year. Which of the following functions best models the population p(t) of jackrabbits t years after 1788?
