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]

y - y1 = m(x- x1)

y - (-5) = 2/3(x -0)

y + 5 = 2/3x

y = 2/3x - 5

if you use photomath right away it will give you the answer not like this app that you have to wait for people.
