Question

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


Pls help :(

Answer 1

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]
