Question

If a function is defined by the formula y = 2x +1 and the domain is given by the set {3, 5, 7,9}

then which set below represents the range of the function?
(Please help)

Answer 1

The range is {7, 11, 15, 19}

Explanation:

Substitute the domain values in the formula

2x + 1

2(3) + 1 = 7

2(5) + 1 = 11

2(7) + 1 = 15

2(9) + 1 = 19
