Write the equation of the parabola in vertex form.

y = (x+3)² - 4

y = (x - a)² + b

where (a,b) is the upper/lower point of the curve

If you still dont understand, look at pic for more example.

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
