Answer:
D
Step-by-step explanation:
The range of a function are the possible y-values (output values).
Options A and B are wrong, because the x-values are the input values.
The range is between -5 and -1 as shown in the graph (y-axis). The circle on the points are shaded so ‘≤’ is correct. Option C is wrong.
The range is greater than or equal to -5 and less than or equal to -1.
Answer:
a cone would be formed due to the point on the graph forming a triangle, and when a triangle is spun around an axis on one of its sides it will form a cone

Hey there!
f(x) = 7/x
<em>~ Simply keep the "7" in the place where "x" is there.</em>
Therefore, X= 1.

Answer:
z=(sqrt(10)-1)/2 or z= -(sqrt(10)-1)//2
Step-by-step explanation:
To complete the square, the last term has to be 1. So adding 10 to both sides, we get:
4z^2+4z+1 = 10
Since 4z^2+4z+1=(2z+1)^2,
(2z+1)^2 = 10.
Taking the square root of both sides, we get
2z+1=sqrt(10) or 2z+1=-sqrt(10)
So z=(sqrt(10)-1)/2 or z= -(sqrt(10)-1)//2
