Question

F(x)=x+7

If you know that the domain is {-10,-5} then the range must be {__,__}

Answer 1

[-3, 2]

Explanation:

Plug in the x values into the equation and evaluate...

f(-10) = -10 + 7 = -3

f(-5) = -5 + 7 = 2

Since f(x) is a continuous line, the range with constantly increase as x increases, so we know that this is the range over that domain.
