Question

If f(x)3(=- Vx-3, complete the following statement:x + 2f(19) ==Answer here

Answer 1

Step-by-step explanation

This exercise is about evaluating a function at a particular argument. To do that, we replace the variable with the argument in the formula of the function, and simplify.

Let's do that:

`\begin{gathered} f(19)=(3)/(19+2)-\sqrt[]{19-3}, \\ \\ f(19)=(3)/(21)-\sqrt[]{16}, \\ \\ f(19)=(1)/(7)-4, \\ \\ f(19)=(1-28)/(7), \\ \\ f(19)=-(27)/(7)\text{.} \end{gathered}`Answer
`f(19)=-(27)/(7)\text{.}`
