Answer 2

To find the values of 'a' for which the function's value is equal to -7, we can simply set the function equal to -7 and solve for 'a':

y = -3 - a

Setting y = -7:

-7 = -3 - a

Now, let's solve for 'a':

-7 + 3 = -a

-4 = -a

To isolate 'a', multiply both sides by -1:

a = 4

So, when 'a' is equal to 4, the value of the function is -7.
