Final answer:
To find the expression for f(x) in terms of x given g(x), we substitute g(x) into the equation f(x) = g(x). The expression for f(x) is f(x) = 2/√(x+7) + 1.
Step-by-step explanation:
To write an expression for f(x) in terms of x, we need to find the value of f(x) in the given equation. The given function is g(x) = 2/√(x+7) + 1. Therefore, to find f(x), we substitute the given function into the equation: f(x) = g(x). So, the expression for f(x) is: f(x) = 2/√(x+7) + 1.
