Where y is amount of money in 1000 dollars

           x is time in months

We are given that α = 4.2 and  β = 1.03 and x = 6 months

Therefore, based on this model, y = αβˣ, the amount he would have in 6 months, y = 4.2*(1.03) ^{6}

y = 5.015 × 1000 = $ 5,015

The points plotted below satisfy a polynomial equation. What type of extreme value does the graph have in the part that is visib
bezimeni [28]
Hi!

The graph shows an A) Maximum

A Maximum value appears in a graph when all other values of the polynomial are smaller in value i.e. are under it in an X-Y plot. This is expressed mathematically as:

There is a maximum if for a given x*: f(x*) ≥ f(x) for all x. 

In the graph, you can clearly see that there is a value that is higher than all the others, so this value is a Maximum.
