Answer:

1st fog =  [tex]9x^{2} - 45x + 52[/tex]

    gof =  [tex]3x^{2} - 15x + 1[/tex]

2nd fog (-2) = -5

       gof ( 1 ) =  115

Step-by-step explanation:

How to solve composite function is easy.

Let's presume f(x) = x^2 - 5x+2 and g(x) = 3x - 5

Find fog(x)

I. Place f(x) = x^2 - 5x +2

II. Replace x value with g(x)

                  =(3x - 5)^2 - 5(3x-5) +2

                  = 9x^2 - 30x +25 - 15x + 25 + 2

                  = 9x^2 - 45x + 52

III. If x value (x) = 1, you just replace x with 1

                  = 9( 1^2 ) -45( 1 ) + 52

                  = 9 - 45 + 52

                  = 16

 So fog(1)  = 16
