Question
Find domain and range of
F (X)=1/✓(x-5)
F (X)=1/✓(x-5)
Open in App
Solution
f(x)=1/√x-5
√x-5≥0
=>x-5≥0 =>x≥5
Domain=[5,∞)
y= 1/ √x-5
y^2=1/x-5
Since the values of y are all greater than zero, Range =(0,∞)
f(x)=1/√x-5
√x-5≥0
=>x-5≥0 =>x≥5
Domain=[5,∞)
y= 1/ √x-5
y^2=1/x-5
Since the values of y are all greater than zero, Range =(0,∞)
