If f(x) - VX-3, complete the following statement (round your answer
to the nearest hundredth):
x + 2
f(7) =

Answer 1

Answer:

≈ - 1.67

Step-by-step explanation:

Substitute x = 7 into f(x) , that is

f(7) = $\frac{3}{7+2}$ - $\sqrt{7-3}$

     = $\frac{3}{9}$ - $\sqrt{4}$

     = $\frac{1}{3}$ - 2

     = $\frac{1}{3}$ - $\frac{6}{3}$

     = - $\frac{5}{3}$

     ≈ - 1.67 ( to the nearest hundredth )
