Given the functions, f ( x ) = x2 + x - 5 and g ( x ) = 4 x2 - 2 x + 1, perform the indicated operation. When applicable, state the domain restriction. ( f - g )( x )

(f-g)(x)  =  - 3 x² + 3 x -6

Step-by-step explanation:

Explanation:-

Given function f(x) = x² + x - 5

                      g(x) = 4 x² - 2 x + 1

(f-g)(x)   =  f(x) - g(x)

            =  x² + x - 5 - (4 x² - 2 x + 1)

            = x² - 4 x² + x + 2 x - 5 -1

            =  - 3 x² + 3 x -6

(f-g)(x)  =  - 3 x² + 3 x -6

  about 5.6 days

step-by-step explanation:

we can fill the given information into the decay equation and solve for the value of t at which half the sample remains.

the half-life is about 5.6 days.

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total
