5.Find the domain of the following function:

y=x+2

x^2 + 2x −8

Select the appropriate response:

A) x equals −4, 2
B) x cannot equal −4, 2
C)Not possible to solve

(-∞,∞)

B) x cannot equal -4, 2

Step-by-step Explanation:

The function, y = x + 2, has a domain of (-∞,∞) because the equation will remain true no matter number you plug for x.

For the second question, x would be equal to -2 and 4.  You can find this by factoring the equation.  x² + 2x - 8 = (x - 2)(x + 4)  Your answer should be B

B) x cannot equal −4, 2

Step-by-step explanation:

x² + 2x - 8 = 0

When x = -4, 2

When the denominator becomes zero, function becomes undefined

24/56=hx^7

step-by-step explanation:

you could deduce the conclusion directly using the facts pertaining to the specific situation.
