The table gives estimates of the world population, in millions, from 1750 to 2000. year population year population 1750 790 1900 1650 1800 980 1950 2560 1850 1260 2000 6080 (a) use the exponential model and the population figures for 1750 and 1800 to predict the world population in 1900 and 1950. compare with the actual figures

The exponential function is given by y = 790(1.004)ˣ

An exponential function is given by:

y = abˣ

where y, x are variables, a is the initial value of y and b is the multiplier.

Let y represent the population in millions after x years above 1750.

At 1750 (x = 0):

790 = ab⁰

a = 790

At 1800 (x = 50)

980 = 790(b)⁵⁰

b = 1.004

The exponential function is given by y = 790(1.004)ˣ

At 1900 (x = 100):

y = 790(1.004)¹⁰⁰ = 1215

At 1950 (x = 150):

y = 790(1.004)¹⁵⁰ = 1438

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
