Okay so in this question it says to solve f(7). This means to plug in the 7 every where you see an x, so that it looks like this: [tex]\frac{3}{7+2} -\sqrt{7-3}[/tex]Then you'll solve it like a normal equation.

Hope this helped! Let me know if there is anything I need to clarify or explain more in depth!

Answer:

- 1.67

Step-by-step explanation:

To evaluate f(7) substitute x = 7 into the expression

f(7) = [tex]\frac{3}{7+2}[/tex] - [tex]\sqrt{7-3}[/tex]

     = [tex]\frac{3}{9}[/tex] - [tex]\sqrt{4}[/tex]

     = [tex]\frac{1}{3}[/tex] - 2

     = [tex]\frac{1}{3}[/tex] - [tex]\frac{6}{3}[/tex]

     = - [tex]\frac{5}{3}[/tex] ≈ - 1.67
