Question

F (x) +5 x-2 Someone pls help me I’m crying

Answer 1

Given the function:

`f(x)=2x^2+5\sqrt[]{x-2}`

to find f(3), we have to make x = 3 and substitute on the function, to get the following:

`\begin{gathered} f(3)=2(3)^2+5\sqrt[]{3-2}=2(9)+5\sqrt[]{1}=18+5=23 \\ \end{gathered}`

therefore, f(3)=23
