Question

Suppose that v(x) = sqrt(2x+1) and f(x) = sort(x). Find a function g(x) such that v(x) = f(g(x))

Answer 1

if \(f(x)=\sqrt{x}\), then what would \(f(2x+1)=\)

Answer 2

that is where I get confused on these problems... is how to substitute into the function

Answer 3

my exam on this is coming up tuesday
