Two functions and are given below f(x) = 3 −x , x > −4
g (x) = − 3 + √2, x> 0
(a) Find the composite function f g(x) stating its domain and range. [5]
(b) Sketch the graph of y = f g(x).

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

i dont know

step-by-step explanation:

add an image, and i will answer

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
