<h3>Quadratic function</h3>Quadratic functions are function that has a leading degree of 2. Given the quadratic equation
y = x^2 - 6x - 16
Factorize
y = x^2 - 6x - 16
y = x^2 - 8x + 2x - 16
y = x(x - 8) + 2(x-8)
y = (x+2)(x-8)
The graph of the function is attached below

Answer:
Yes
Step-by-step explanation:
Given that a relation R is defined on the set Z by "a R b if a - b is divisible by 5
for a, b in the set of integers.
Reflexive:
We have
for any a,
i.e. (a,a) is related. Hence reflexive
ii) Symmetric:
If a-b is divisible by 5, then b-a is also divisible by 5. Hence symmetric
iii) Transitive
If
adding we get
Hence R is transitive
It follows that R is an equivalence relation on Z
