drag the items to categorize them as functions or not functions.

my keyboard is broken. sometimes when i press the "h" key, a "u" shows up on the screen. other times, a "g" shows up. weird.

when i turn the knob left, the door locks every time.

The second condition is a function.

'When I turn the knob left, the door locks every time.'

Step-by-step explanation:

We know function is a special type of relation in which every element of a set ( Here set A(let) includes {H} in first condition and {turning the knob} in second condition) is related to other set (Here set B(let) includes {output U and G} in first condition and{locking of door}in second condition) in such a way that every element of set A have one and only one image in set B.

Here,

In condition 1 one element of set A(pressing key H) have two image(output U and G both)

[which do not satisfies the condition for being a function.]

In condition 2 one element of set A(turning knob left) have only one image(locking of door every time.)

[which satisfies the condition of being function]

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
