Find g7 fx 3x 1 gx 2f x 6 Find hhx hx x2 4Solution13 g

Find g(7) f(x) = 3x - 1 g(x) = 2f (x - 6) Find h(h(x)) h(x) = x^2 + 4

Solution

13)

given,

g(x)= 2f(x-6)

so, g(7) = 2f(1)...........a)

also,

f(x)= 3x-1

so, f(1)=2 ... put in eqn. a)

we get , g(7)= 4.

14)

given , h(x) =x² +4

so,putting h(x) instead of x in above we get;

h(h(x)) = (x² +4)² +4 = x⁴ +8x² + 20
