Find f(g(x)) f(x)=4x-8 , g(x)=6x-4

f (x) (g (x)) f (x) = 4 x - 8, g (x) = 6 x - 4

36 \circ x^{2} f (x)^{2} - 48 \circ x f (x)^{2} + 16 \circ f (x)^{2}

Solution steps

Find

f (x) (g (x)) f (x) \circ g

given

f (x) (g (x)) f (x) (x) = 4 x - 8, g (x) = 6 x - 4

f (x) (g (x)) f (x) \circ g = f (x) (g (x)) f (x) \circ g (x)

g (x) = 6 x - 4

g (x) = 6 x - 4

= f (x) (6 x - 4) f (x) \circ (6 x - 4)

Expand

f (x) (6 x - 4) f (x) \circ (6 x - 4) : 36 \circ x^{2} f (x)^{2} - 48 \circ x f (x)^{2} + 16 \circ f (x)^{2}

= 36 \circ x^{2} f (x)^{2} - 48 \circ x f (x)^{2} + 16 \circ f (x)^{2}

4 x - 3 y = 24

f (x) = 3 x^{2} - 30 x - 8

f (x) = 3 x - 6, (0, 4)

(4, 6), (- 1, - 14)

x = 1 f (x) = - 2 x^{2} - 3 x, x = 1
