Look at the picture.

The angle y° and 71° are Supplementary Angles. Therefore y° + 71° = 180°.

$y^o=180^o-71^o=109^o$

The sum of measures of these three angles of any triangle is invariably equal to 180°.

Therefore we have the equation:

$x^o+109^o+28^o=180^o\\\\x^o+137^o=180^o\ \ \ |-137^o\\\\x^o=43^o$

The plot below shows the graphs of three functions, f, g, and h, all of which determine the population of three different cities

So, here we have an exponential function.

Remember that an exponential function has the form:

$y=a(b)^x=a(1\pm\frac{r}{100})^x$

Where a represents an initial amount, and r is the rate of this amount to change. (Increase, or decrease).

So, given that the population of City A in 2000 was 40 thousand people and the population increased by 13% each year, we can say that

$\begin{gathered} a=40 \\ b=1+\frac{13}{100}=1.13 \end{gathered}$

So,

$f(x)=40(1.13)^x$

For city B:

$\begin{gathered} a=40 \\ b=1+\frac{16}{100}=1.16 \\ g(x)=40(1.16)^x \end{gathered}$

But something different happens with city C. This is not an exponential function, this is a linear function.

So,

$h(x)=40+10x$
