Answer:

A. No; two range values exist for domain value –2.

Step-by-step explanation:

In a function each input has ONE output. -2 has two range values, so No; two range values exist for domain value -2.

The given relation is

We need to check whether the above relation is a function or not.

A relation is a function if there exist a unique value of y for each value of x.

From the given relation it is clear that

y = 0 at x = -2

y = 6 at x = -2

Two range values exist for domain value –2. So, the given relation is not a function.

RUDIKE [14]

$\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}$

Given - an equation in it's general form

To do - convert the given equation into a form that is easy to solve

Given equation -

$\bold{(x + 2) {}^{2} + 4(x + 2) - 5 = 0} \\$

solve the parenthesis so as to obtain simpler terms

$\bold{\implies \: ( x {}^{2} + 4x + 4 ) + 4x + 8 - 5 = 0}\\$

solve the like terms and you'll obtain the required equation !

$\bold{\implies \: x {}^{2} + 8x - 7 = 0}$
