A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation. Using this equation, find out the maximum amount of profit the company can make, to the nearest dollar. y=-x^2+78x-543 y=−x 2 +78x−543

978

Step-by-step explanation:

y= -x²+ 78x - 543

y= ax²+ bx + c

a= -1, b= 78, c= -543

max = c -(b²/4a)

= -543 -(78²/-4)

= -543 + 1521

= 978

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.
