Find the maximum of y=-x^2-4/3x +5

49/9

y=-x^2-4/3x+5

(h,k)

h = minimum

k/y = maximum

h = -b/2a

a = (-1)x^2

b = (-4/3)x

h = 4/3 / -2 = -2/3

To find the maximum, take the minimum and replace it with every "x" in the equation.

y = -(-2/3)^2-4/3(-2/3)+5

y = 49/9

try quizlet : ) hope this

b

step-by-step explanation:

this is because the profit is decreasing and turning into debt
