I am soo confused about this question!!

I think it’s just asking you to add the two functions (f + g)(x)

If f(x) = sqrt x + 3
And g(x) = x + 2

Then (f + g)(x) = (sqrt x + 3) + (x +2)

And I’m pretty sure that’s all you can simplify

The coordinates of point a right now is (-3,-1) you have to multiply these coordinates by a factor of 2 to get (-6,-2)
