Question

Find the range of the function for given domain f(x)=2x-7; (-2,-1,0,1,2)

Answer 1

Answer:

  {-11, -9, -7, -5, -3}

Step-by-step explanation:

Put each domain value into the function to find the corresponding range value. The range is the list of all of those values.

__

  range = f(domain)

  = 2{-2, -1, 0, 1, 2} -7 = {-4, -2, 0, 2, 4} -7

  = {-11, -9, -7, -5, -3} . . . . . the range for the given domain
