What is the inverse of this function?

The inverse function will be x = (y) = 4 +  

Step-by-step explanation:

Given,

y =

To find the inverse of this function means we have to find the value of x in terms of y

Now,

y =

or, y - 2 = [ subtracting 2 from both side]

or, (y-2)(x-4) = a [ by cross multiplication)

or, x-4 =

or, x = 4 +

Hence, x = (y) = 4 +  

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
