G(x)-x^3+5x, f(x)-4x+5 find g(x)+f(x)

Find g(f(x)) f(x)=4x-5 , g(x)=(x+5)/4. f(x)=4x−5 f ( x ) = 4 x - 5 , g(x)=x+54 g ( x ) = x + 5 4. Set up the composite result function. g(f(x)) g ( f ( x ) ).

let me know if this helps??

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
