Question

Using a table find the range of the function for given domain f(x)=2x+7 with domain x=2,3,5,9​

Answer 1

Range : {11,13,17,25}

Explanation:

Given

f(x) = 2x+7

and

Domain = {2,3,5,9}

To find the range, the values in domain will be put in the function one by one

So,

f(2) = 2(2)+7 = 4+7 = 11

f(3) = 2(3)+7 = 6+7 = 13

f(5) = 2(5)+7 = 10+7 = 17

f(9) = 2(9)+7 = 18+7 = 25

Therefore the range is {11,13,17,25} ..
