Answer:
Range : {11,13,17,25}
Step-by-step 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} ..
