Question

3 is an element in the domain of the function g(x)= -2x - 4 . What is the corresponding element in the range?

Answer 1

Hello! :)

$\large\boxed{g(3) = -10}$

If 3 is apart of the domain, then x = 3.

The range is equivalent to g(x), or the y-value. To solve for this when x = 3, we must plug 3 into the equation:

g(x) = -2x - 4

g(3) = -2(3) - 4

Simplify:

g(3) = -6 - 4

g(3) = -10
