Question

If f(x) = 3/x+2 - √x-3, complete the following statement (round to the nearest hundredth) f(7)=

Answer 1

f(7) = -5/2

Explanation:

Substituting 7 for x in f(x) = 3/x+2 - √x-3, we get:

f(7) = 3/(7+2) - √(7-3)

Note: the parentheses are required / mandatory

We get f(7) = 3/9 - 2, or 1/3 - 2, or f(7) = -5/2
