Question

A function, f(x) = 4x + 5, has a domain 0 < x < 50. What is its range?

Answer 1

Answer:

f(x) = 4x+5 ; 0 ≤ x ≤ 50

 

The range is the possible output values of f(x)

 

4(0) + 5 = 5       smallest output value in range

4(50) + 5 = 55    largest output value in range

 

The outputs are between 5 and 55 including the endpoints so

the range is [5, 55]

Answer 2

The range is [5,55] for this question
