In the following function f(k) = -4/k+7, what value of k would be excluded from the domain?

-7

Step-by-step explanation:

We cannot have 0 in the denominator, as any number divided by 0 results in undefined. So we can solve this by using

k+7 = 0 which results in k= -7. So if k is -7 that will result in -4/0 and will result in undefined so we will exclude -7 from the domain of k.

answer is x<
