Answer: 1 1/2 hours or 90 minutes
Step-by-step explanation: Painting 1/2 of her bedroom took 3/4 an hour or 45 minutes. At the same rate, it would take her another 3/4 of an hour or 45 more minutes. Add it together to get 90 minutes or 1.5 hours to paint the full room.
g(x)=x2+2

(f⋅g)(x)=
The value of the composition of function ( f . g )( x ) = x⁵ - 2x³ + 2x² - 8x + 4
Evaluation of a function at the value of another function is known as Composition of function. A function composition is a process in which two functions, f and g, form a new function, h, in such a way that h(x) = g(f(x)). This signifies that function g is being applied to the function x. So, in essence, a function is applied to the output of another function.
Given data ,
Let the first function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = x³ - 4x + 2
Let the second function be represented as g ( x )
Now , the value of g ( x ) is
g ( x ) = x² + 2
Now , the composition of function ( f . g ) ( x ) = f ( x ) . g ( x )
On simplifying , we get
The composition of function ( f . g ) ( x ) = ( x³ - 4x + 2 ) ( x² + 2 )
A = x³ ( x ² ) - 4x ( x )² + 2x² + 2x³ - 8x + 4
A = x⁵ - 4x³ + 2x² + 2x³ - 8x + 4
On further simplification , we get
A = x⁵ - 2x³ + 2x² - 8x + 4
Hence , the composition of function is A = x⁵ - 2x³ + 2x² - 8x + 4
