Find f(g(h(x))) from functions below..
Lilit [14]

Answer:

f(g(h(x))) = (\sqrt{x} - 8)^4 + 8

Step-by-step explanation:

f(x) = x^4 + 8

g(x) = x - 8

h(x) = \sqrt{x}

f(g(h(x))) = f(g(\sqrt{x})) = f(\sqrt{x} - 8) = (\sqrt{x} - 8)^4 + 8

The cube root function shift left 2 and up 3
ivolga24 [154]

Answer: f(x) = 3\sqrt{x+2} +3

Step-by-step explanation: 3\sqrt{x+2} +3

(assume that the three in front is a part of the cube root function)

In order to shift a parent function to the left two you need to add it on the inside (in this case underneath the cube root). Adding on the inside does the opposite if you were adding on the outside, so instead of moving it to the right, it moves it left. In order to slide a function up or down you need to add or subtract a number on the outside of the function. In this case you need to add 3 at the end.
