It would be a five
Step-by-step explanation:
Answer:
15
Step-by-step explanation:
Since range is the difference between the highest valued character and the smallest
20-5=15
The picture in the attached figure
we know that
case a) f(x)=3x
the domain is all real numbers------> interval (-∞,∞)
case b) f(x)=√x
the domain is <span>all real numbers greater or equal than 0
the interval [0,</span>∞)
case c) f(x)=3x+4
the domain is all real numbers------> interval (-∞,∞)
case d) f(x)=1/√(x-3)
<span>the denominator can not be zero and can not be negative
</span>so
(x-3) > 0-----> x > 3-----> the domain is <span>all real numbers greater than 3
</span>the interval is (3,∞)
the answer isf(x)=1/√(x-3)
