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

The maximum value of is (0, f (0) = Undefined)

49/9

Step-by-step explanation:

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
