F(x) =x^2-4x+2 and g(x) =3x-7 find (fog)(x)

9x² - 54x + 79

Step-by-step explanation:

To find (f ￮ g)(x) substitute x = g(x) into f(x), that is

f(g(x))

= f(3x - 7)

= (3x - 7)² - 4(3x - 7) + 2 ← expand factor using FOIL

= 9x² - 42x + 49 - 12x + 28 + 2 ← collect like terms

= 9x² - 54x + 79

Step-by-step explanation:

hello :

F(x) =x²-4x+2 and g(x) =3x-7

(fog)(x)=f(g(x))=f(3x-7) = (3x-7)²-4(3x-7)+2

(fog)(x)= 9x²-42x+49-12x+28+2

in standard form : (fog)(x)= 9x²-54x+79

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

mean, 40.6
