If f(x)=3/x+2-square root x-3\sqrt[x - 3]{?}

Question

If f(x)=3/x+2-square root x-3
`\sqrt[x - 3]{?}`

Answer 1

`\begin{gathered} f(x)\text{ = }\frac{3}{x\text{ +2}}\text{ }\sqrt[]{x\text{ -3}} \\ To\text{ find f(7)} \end{gathered}`

Step 1: comapre f(x) to f(7)

f(x) = f(7)

which means x = 7

Step 2
