Answer:
Step-by-step explanation:
f(x) = -5x + 5
g(x) = 8 + 2x
a) (f + g)(x) = f(x) + g(x)
= (- 5x + 5) + ( 8 + 2x )
= - 5x + 2x + 5 + 8
= - 3x + 13
b) (f - g)(x) = f(x) - g(x)
= ( -5x + 5 ) - ( 8 + 2x)
= - 5x + 5 - 8 - 2x
= - 7x - 3
c) (f + g)( 4 )
(f + g)( x ) = - 3x + 13
(f + g) ( 4 ) = - 3 ( 4 ) + 13
= - 12 + 13
= 1
d)(f - g)(- 3)
(f - g) ( x ) = - 7x - 3
(f - g) ( - 3 ) = - 7 ( - 3 ) - 3
= 21 - 3
= 18

Answer:
DNE
Step-by-step explanation:
An even-degree polynomial with a positive leading coefficient has no upper bound. The upper bound does not exist (DNE).
