Step-by-step explanation:
Let the required number be n
NOTE: A number is always 100% in itself.
Answer:
f(x)= (x+8)^2 + 200
Step-by-step explanation:
-b/2a gives you the x coordinate of the vertex and then plug it in for x to get the y coordinate. Put it in the formula (f()x= (x-h)^2 +k).
H is the x coordinate and K is the y coordinate
The solution is y = -5
What is Quadratic Equation?
A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c = 0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
Given data ,
Let the function be f ( x ) = y
And , y = x² + 2x - 8
So , f ( x ) = x² + 2x - 8
Substituting the value for x in the equation , we get
When x = -3
f ( -3 ) = ( -3 )² + 2( -3 ) - 8
= 9 - 6 - 8
= 9 - 14
f ( -3 ) = -5
When x = 1
f ( 1 ) = ( 1 )² + 2( 1 ) - 8
= 1 + 2 - 8
= 3 - 8
f ( 1 ) = -5
Hence , the value of y = -5

Which is a subset of [1,2,4,5,6]? <br>
A. [0,1,2]<br>
B. [3,4]<br>
C. [5,6,7]<br>
D. [2,6]

Answer: D, [2,6])
Step-by-step explanation
Let us start by explaining what a subset means. A subset of a set is a a set(usually a smaller set) that contains contains elements which are all members or elements of the main set. This means that all the elements in the subset are contained in the main set. Usually, all the elements of the subset are contained in the main set but all the elements in the main set are not contained in the subset
The given set of numbers is
[1,2,4,5,6]
From the options given, all the elements in the subset, [2,6] are contained in the main set, [1,2,4,5,6].
So option D is the subset.
The subsets in the other options has elements that are not in the main set.
