Question

use the following functions:
f(x) = x + 5
g(x) = x2 -4x + 5
h(x) = 3x2 - 2x + 5


find: f [g(2)]

Answer 1

g(2) = (2)^2 - 4(2) +5 = 1
f(g(2))= f(1) = 6

therefore f(g(2)) = 6

Answer 2

wheres the 2 come from for the x values in the g equation?

Answer 3

g(2) will be the input of f(x)
so x of f(x) will be g(2)
