Maximum value of the function f(x)=-x²-6x-17

Step-by-step explanation:

y = -x^2 + 6x - 17

y = -(x^2 - 6x) - 17

y = -(x^2 - 6x + 9 - 9) - 17

y = -(x^2 - 6x + 9) - 17 + 9

y = -(x - 3)^2 - 8

The maximum value is -8 for x = 3.

You multiply the side of the triangle 2 cm by the number of sides their are 5 and your answer should be 10. Similarly, the larger shape has a side length of 3 cm times the number of sides there are 5 and you get 15 cm which is what is shown as the perimeter of the bigger shape.
