Answer:
(- ∞, 4 ]
Step-by-step explanation:
To determine the range we require the coordinates of the vertex
The vertex lies on the axis of symmetry which is positioned at the midpoint of the zeros.
To obtain the zeros, equate f(x) to zero, that is
-(x + 5)(x + 1) = 0
Equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
x + 1 = 0 ⇒ x = - 1
=
=
= - 3
Substitute x = - 3 into f(x) for corresponding value of y
f(- 3) = - (- 3 + 5)(- 3 + 1) = - (2)(- 2) = 4
Vertex = (- 3, 4)
Since a = - 1 then vertex is a maximum, hence
range is (- ∞, 4 ]
Answer:
x-int= (18,0), y-int= (0,-6)
Answer:
Option d) x = 25
Step-by-step explanation:
we have

Solve for x
Subtract 4 both sides


squared both sides


Adds 9 both sides



<u><em>Verify </em></u>
1) For x=25


----> is true
therefore
x=25 is a solution
2) For x=-7


The radicand cannot be a negative number
therefore
x=-7 is not a solution
Answer:
3 x 7 = f

I HOPE THIS HELPS YOU OUT WITH YOUR QUESTION! PLZ LET ME KNOW IF IT DID! IT MAKES ME FEEL GOOD THAT SOMEONE APPRECIATES IT! ANYWAY, IF YOU HAVE A FEW MINUTES PLZ GOT TO MY PROFILE AND THANK MY ANSWERS (THE MORE THE MERRIER)
I think the critters ate 5 1/2 packages of Toni’s oatmeal.
If he ate half as much as the others you should total up the others and divide it by 2.
3 + 2 + 6 = 11 11 divided by 2 = 5 1/2
I hope you find this helpful.
