(x + 2)2 + (y + 3)2 = 0 where x and y are real numbers.
Each parenthesis is a square number and so MUST be greater than or equal to zero, so their sum can be zero only if each parenthesis is zero.
The square of the expressions in the parentheses can be zero only if the expressions themselves are zero and hence the result.

No.
f(x) = 2*(x-3)*(x+2)/(x-1) for x ≠1
3.
y = 5x + 3When x=2,y = 5(2) + 3 = 10 + 3 = 13
First, this function is strictly increasing on the entire real line, so an inverse exist on the entire real line. We define inverse of function f, denoted f^-1 such that if y = f(x) then f^-1(y) = x Or to find the inverse, all is needed is to isolate x in terms of y. In this case, y = 7x + 2 7x = y - 2 x = (y - 2)/7 So the inverse is x = (y - 2)/7 What? You don't like function in terms of y? Well, they are just meaningless variables anyway, you can write whatever, in particular the inverse is y = (x - 2) / 7 (the x, y here are independent with the x, y above. If you are getting confused, write b = (a - 2)/7 where b is a function of a)
Something like "Write a false statement".
y = 2, 4, 6, 8
y = 8 - 2*x
The function rule for this is (1) it is a variable or phantom any letter that stands on its own is a phantom here is a example =Y(2x + 2x)=2=2=4x + Y=5 (I am a grade 8 i know how you feel)
x + y = -2 y = -x - 2 f(x)= - x -2
The answer is A = 2.

g = f(x) = 3x + 2
Yes.
A polynomial of degree 2.
Yes, y=-2+x is a linear function.
