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

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

i think it is c, not positive though
