Answer:
[f(2) - g(1)]² = 1
Step-by-step explanation:
Using the given functions:
f(x) = x² + 1
g(x) = 3x + 1
We can use the given values of 'x' to solve each function and then the combined function. f(2) means the value of 'x' =2 and g(1) means the value of x=1:
f(2) = 2² + 1 = 4 + 1 = 5
g(1) = 3(1) + 1 = 4
[f(2) - g(1)]² = (5 - 4)² = 1² = 1
