You most likely only need the first 3 digits after the decimal point but if you needed more i added them! hope this helps
Answer:
Option d is right
Step-by-step explanation:
A function is called one to one if two x will not have same y value.
In other words, in the domain each x is matched with a unique y and if x1 not equals x2 we have the corresponding y1 will not be equal to y2.
In the graph given, we find that the y value say 1 has preimages in both to the right of y axis and to the left of y axis.
Hence this is not one to one.
This is a function because each x has a unique image. If we draw a vertical line in any part of the graph we find that it cuts only one time the graph of f(x)
Hence f is a function but not one to one. A one to one function need not pass through the origin.
Hence we find that of the options given, a,b and c are wrong.
But option d is right.
Answer:
midpoint (5,4)
Step-by-step explanation:
The midpoint(M) of a segment with endpoints (x₁ , y₁) and ( x₂, y₂) is
where x₁ = 2 and x₂ = 8
y₁ = 0 and y₂ = 8
M = 
M = 
M = 5 , 4
Answer:
6
Step-by-step explanation:
so this is (base times hight)
(bH)
42=7x
you didvide 7 from both sides
42 divided by 7 is 6
so basically its 6
because that would be your base thats what you are missing
then its just baseically (BH) (7 times 6)= 42
if this is wrong im so sorry I just learned this good luck
Answer:
f(n) = -n^2 -3n +5
Step-by-step explanation:
Suppose the formula is ...
f(n) = an^2 +bn +c
Then we have ...
f(1) = 1 = a(1^2) +b(1) +c
f(2) = -5 = a(2^2) +b(2) +c
f(3) = -13 = a(3^2) +b(3) +c

Here's a way to solve these equations.
Subtract the first equation from the second:
-6 = 3a +b . . . . . 4th equation
Subtract the second equation from the third:
-8 = 5a +b . . . . . 5th equation
Subtract the fourth equation from the fifth:
-2 = 2a
a = -1
Then substituting into the 4th equation to find b, we have ...
-6 = 3(-1) +b
-3 = b
and ...
1 = -1 +(-3) +c . . . . . substituting "a" and "b" into the first equation
5 = c
The formula is ...
f(n) = -n^2 -3n +5
