The number of banks in a country for the years 1935 through 2009 is given by the following function 83.7x + 12,362 if x < 90
f(x) =
where x is the number of years after 1900
376.8x +48,688 if x 290

The number of banks in 1960 is

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

the height of the surface increases from the center out to the sides of the road

it is c!

1332.

this is because to get from 333 to 999 you multiply by 3, and you should do the same to the number of hours.

therefore you would do 444*3=1332
