Which combination could create the function f(x)= x√x?

adding a rational function and a linear function
adding a linear function and a logarithmic function
multiplying a linear function and a square-root function
dividing an exponential function and a logarithmic function

clearly, there us no addition or division involved, right?

To determine the correct combination, we need to analyze the given function f(x) = x√x.

Looking at the function, we can identify that it involves both a linear term (x) and a square root term (√x). The x term is straightforward, as it is a linear function. However, √x requires a square root function.

Among the provided combinations, only the option "multiplying a linear function and a square-root function" satisfies the requirements for creating the given function f(x) = x√x.

Therefore, the correct combination that creates the function f(x) = x√x is multiplying a linear function and a square-root function.
