The resulting composite function (f∘f)(x) is x⁴+2x²+2
When a function is written inside another function, it is known as a composite function
Given the function f(x)=x²+1,
(f∘f)(x) = f(f(x))
f(f(x)) = f(x²+1)
This means we will need to replace x with x²+1 in f(x) as shown:
f(x²+1) = (x²+1)²+1
Expand
f(x²+1) = x⁴+2x²+1+1
f(x²+1) = x⁴+2x²+2
Hence the resulting composite function (f∘f)(x) is x⁴+2x²+2

Answer:
572.4 m
Step-by-step explanation:
Fórmula del ángulo de elevación =
tan θ = Opuesto / Adyacente
θ = 3 °
Opuesto = 30 m
Adyacente =?
Por eso
bronceado 3 = 30 m / x
Multiplicar cruzada
bronceado 3 × x = 30 m
x = 30 m / bronceado 3
x = 572.43410063m
Aproximadamente = 572.4 m
Answer: You do not because the tv costs $464.
Step-by-step explanation:
First find out how much 20% of 580 is:
= 20% * 580
= $116
The television was therefore marked down by $116. The current selling price is:
= 580 - 116
= $464
<em>Since you came with $450, you will not be able to buy the television as you would be short of the $464 required. </em>
