  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]

    Step-by-step explanation:
