The whole numbers from 10-12 are paired with their factors explain why this pairing doesnt describe a function

myrzilka [38]

Answer:

As given whole numbers from 10 - 12 are paired with their factors.

factor of ,10=1,2,5,10 → (10,1),(10,2),(10,5)(10,10)

factor of 11=1, 11 → (11,1),(11,11)

factor of 12=1,2,3,4,6,12→ (12,1),(12,2),(12,3),(12,4),(12,6),(12,12)

As we know for an ordered pair to be function Every element in the domain must have a unique image, i.e it can't have more than one image.

→ As element 10, have four images,which are 1,2,5,10 so it can,t be a function.

Similarly element 11 have two images 1,11 so it can't be a function.

Element 12 have six images 1,2,3,4,6,12, so it also can't be written as function.

What is the range of the function on the graph?all real numbersO all real numbers less than or equal to -1all real numbers less

Yuki888 [10]

The range of the function f(x) is the set of all values that function f takes.

The domain of the function f(x) is the set of all possible values for x.

From the given graph you can see that the domain is all real numbers, $x\in (-\infty,\infty).$

The maximal y-value that f takes is 3 at x=-1. For all another x from the domain, y is less than 3.

Thus, the range of the given function is $y\in (-\infty,3].$

Answer: $y\in (-\infty,3].$
