the two integers 87 between is 86 87 89
Answer:
The graph in the attached figure
Step-by-step explanation:
we have

Using a graphing tool
see the attached figure
This is the equation of a vertical parabola open downward
The vertex is the point (3.25,225) (a maximum)
The zero's of the function or the t-intercepts are the points (-0.5,0) and (7,0)
The h-intercept of the function is the point (0,56)
The domain of the function are all real numbers
The range of the function
----> All real numbers less than or equal to 225
Answer:

Step-by-step explanation:
we have

we know that
The equation of a vertical parabola into vertex form is equal to

where
(h,k) is the vertex of the parabola
and the axis of symmetry is equal to 
In this problem we have the axis of symmetry 
so
the x-coordinate of the vertex is equal to
therefore
For
-----> one unit to the right of the vertex
Find the value of 


For
-----> one unit to the left of the vertex
Find the value of 


Remember that
------> the x-coordinates are at the same distance from the axis of symmetry
so
------> solve for b



Answer:
All real values of x such that x ≥-3
Step-by-step explanation:
g(x) = sqrt(x+3)
A sqrt must be greater than or equal to zero
sqrt (x+3) ≥ 0
Square each side
x+3≥ 0
Subtract 3 from each side
x ≥-3
The restrictions on x are x ≥-3
That means the domain is x ≥-3
All real values of x such that x ≥-3
