Question

Using f(x) = 4x + 6 with a domain of { -1, 0, 2 }, find the range.

Answer 1

{0, 6, 10}

Explanation:

Well let's first graph,

f(x) = 4x + 6

Look at the image below ↓

If some of the domain is {-1, 0, 2},

then some of the range is the range is {0, 6, 10}.

Thus,

the range is {0, 6, 10}.

Hope this helps :)
