Final answer:
To find the composition of three functions, substitute the expression for each function into the composition notation.
Step-by-step explanation:
The composition of three functions f, g, and h can be represented using the notation f o g o h.
To find the expression for this composition, we need to substitute the expression for each function into the composition notation.
The given expression is -2(4x - 10)⁴.
Let's assume h(x) = -2(4x - 10)⁴ as the expression for function h.
Next, we substitute h(x) into the composition notation and find the composition: f o g o h(x) = f(g(h(x))).
