Answer:
≈ - 1.67
Step-by-step explanation:
Substitute x = 7 into f(x) , that is
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 ( to the nearest hundredth )
