Which functions are invertible

choose each correct answer

Top right and top left.

Step-by-step explanation:

For a function to be invertible, we must have that the function is one to one, this is because if we have that the function f(x1) = Y = f(x2)

for the inverse, such that g(f(x1)) = x1

but we know that f(x1) = f(x2)

this means that g(f(x1)) = x2

so g(y) is not a function.

Then, the only functions that can be invertible are the one-to-one functions, the top right, and the top left functions.

its a, i had the same answer, its from study island right

step-by-step explanation:

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
