What figures are you talking about, can you post the picture?
Easy
differnce of 2 perfect squares
a²-b²=(a+b)(a-b)
in this case
x⁴=(x²)²
16=4²
(x²)²-4²=(x²+4)(x²-4)
x²-4 can be factored since 4=2²
x²-2²=(x+2)(x-2)
complete factored form is
(x²+4)(x+2)(x-2)
gegroup to seperate (x+2)
(x+2)[(x²+4)(x-2)]
(x+2)p(x)
p(x)=(x²+4)(x-2)
expanded
p(x)=x³-2x²+4x-8

Answer:
h(x) = x/4
Step-by-step explanation:
To find the inverse of a function, exchange x and y and then solve for y
y = 4x
Exchange x and y
x = 4y
Solve for y
Divide each side by 4
x/4 = 4y/4
y = x/4
The inverse is
h(x) = x/4
