Answer:
See below in bold.
Step-by-step explanation:
y = -x^2 - 2x - 5
Convert to vertex form:
y = -(x^2 + 2x) - 5
y = - [(x + 1)^2 - 1] - 5
y = -(x + 1)^2 + 1 - 5
y = -(x + 1)^2 - 4
So the vertex of the graph is at (-1 , -4) and it is a maximum because the coefficient of x^2 is negative.
So the range is all values of f(x) up to and including -4.
In interval notation this is (-∞, -4].
49
f(5)=8×5+9=40+9=49
its to blurry
Multiply 6 by 60 then divide by two which will get you 180.
