Pls answer asap i’m taking a test ahhh

First, It's a function.

Second, domain is {a,b,c,d}

Third, range is {x,y,z}

Reason why it's function because

1. A single value in Input doesn't have 2 lines connected (domain must not be repetitive.)

2. All Inputs have lines connected to Output (if not then not a function.)

d. is the correct answer

step-by-step explanation:

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

happy to
