Which domain restrictions apply to the rational expression? x^2+4x+4 / x^2−4 Select each correct answer x≠−4 x≠−2 x≠0 x≠2 x≠4
Degger [83]
The correct answers are x≠2 and x≠(-2).

Domain restrictions are any points in the domain where the function will not have a value.  This basically means that it's a point where x won't work in the function.

For the numerator, any value will work for x.  We can have a value of 0 in the numerator, or a positive, negative, or decimal number.

However, the denominator cannot equal 0.  This is because a fraction bar represents division, and we cannot divide by 0.  The values that make the denominator 0 can be found by:

x²-4=0

Add 4 to both sides:
x²-4+4 = 0+4
x² = 4

Take the square root of both sides:
√x² = √4

x = 2 or x = -2.

Mkey [24]

B=2h(a+b) #the numerator goes to the other side, the denominator then just makes it B

B/2h=a+b

2h=a+b/B
