Question 1149567: Since 1950, the world population has risen from 2.5 billion at a rate of 1.8% per year. The equation that represents this exponential function is y=2.5(1.018) raised to x, where x represents the time in years since 1950, and y represents the world population, in billions. Estimate the population in a) 1976, b)2001, and c)2026.

What do you want us to do for you on this?

You are given the function; evaluate it for the given years.

f%28x%29+=+2.5%281.018%29%5Ex

x is years after 1950; so 1976 is x=26, 2001 is x=51, and 2026 is x=76.

Use a calculator and find the answers yourself.

You learn nothing from having us do the calculations and giving you the answers....
