Question

If f = {(2, 3), (5, 7), (3, 3), (5, 4), (9, 1)}, what is the range? {2, 5, 3, 9} {3, 7, 3, 4, 1} all whole numbers {1, 3, 4, 7}

Answer 1

Answer:

Range :  {1, 3, 4, 7}

Step-by-step explanation:

Given function is defined as  f = {(2, 3), (5, 7), (3, 3), (5, 4), (9, 1)},

Now we need to find about  what is the range of the given function f.

we know that y-value corresponds to the range.

since each point is written in (x,y) form so we just need to collect y-values of

f = {(2, 3), (5, 7), (3, 3), (5, 4), (9, 1)},

Hence required range is {3, 7, 3, 4, 1}

But we need to remove repeated values

so correct choice is  {1, 3, 4, 7}
