The graph of the function

is parabola with branches going down in the negative direction of y-axis.
The vertex of parabola has coordinates:

Then you can conclude that all x are possible, that means that the dimain is

and the maximum value of y is at the vertex, then the range is
![(-\infty,6]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C6%5D)
.The function is increasing for x<-2 and decreasing for x>-2 (since vertex is the maximum point).
When x=0, y=2.
Hence,
<span>The domain is {x|x ≤ –2} - false.
</span>
<span>The range is {y|y ≤ 6} - true.
</span>
<span>The function is increasing over the interval (–∞ , –2) - true.
</span>
<span>The function is decreasing over the interval (−4, ∞) - false.
</span>
<span>The function has a positive y-intercept - true.</span>
Answer:
44 units squared.
Step-by-step explanation:
The formula for area of a trapezoid is:

a = missing area
b1 = short base (5)
b2 = long base (17)
h = height (4)
(5 + 17) ÷ 2 = 11
11 × 4 = 44
area = 44
Answer:
x = 33, y = 17
Step-by-step explanation:
1) the sum of all the angles in any triangle is 180 degrees
2) when 2 lines intersect, the angles opposite each other are equal
3) the sum of any angles that break up one side of a straight line is 180
Answer:
11
Step-by-step explanation:
4(s-3)-4=4+8(3)
=4+24
=28
4s-12-4=28
4s-16=28
4s=28+16
4s=44
s=44/4
s=11
Both same unit so multiply your numbers to get a great digits
