Step 1
The function f(x) = √(9x + 45) exists when the expression inside the square root is greater than or equal to 0. So, 9x + 45 ≥ 0. ** Show more…

Determine where the function f (x) is continuous
Sanchit J.
Describe the interval(s) on which the function is continuous. Explain why the function is continuous on the interval(s). If the function has a discontinuity, identify the conditions of continuity that are not satisfied. $$ f(x)=\frac{|4-x|}{4-x} $$
