The answers are that the number can equal -4 or 1. 

You can find this by setting the number equal to x.

x^2 (The square of a number) + 3x (three times a number) = 4

x^2 + 3x = 4 ---> subtract 4 from each side
x^2 + 3x - 4 = 0

Then you can factor this to find the answers

(x - 4)(x + 1) = 0

Set both equal to 0 and solve.

The equation that predicts the population after t years is given as:

y=150\times4^t

Substitute t = 3/2 into the equation

\begin{gathered} y=150\times4^{\frac{3}{2}} \\ y=150\times2^{2(\frac{3}{2})} \\ y=150\times2^3 \\ y=150\times8 \\ y=1200 \end{gathered}

The closest valuie to the value of y is 1200
