What are the domain and range of this function y=(x+3)^2 -5
n200080 [17]

Answer: Choice A

Note: the range should be [-5, \infty). See explanation below.

===================================================

We can plug in any real number for x to get some output for y. The domain is the set of all real numbers in which we say (-\infty, \infty) which is interval notation. It represents the interval from negative infinity to positive infinity.

The range is the set of possible outputs. The smallest output possible is y = -5 which occurs at the vertex (3,-5). We can get this y value or larger. So we can describe the range as the set of y values such that y \ge -5 and that translates to the interval notation [-5, \infty).

The square bracket says "include this endpoint" while the curved parenthesis says to exclude the endpoint. Your teacher mistakenly wrote (-5, \infty) for choice A, when they should have written [-5, \infty)

I think either your teacher made a typo or somehow the formatting messed up. Either way, choice A is the closest to the answer.

Solve 11b^2-9=-68 using the square root method
Vladimir79 [104]

Answer:

b=i*\sqrt{\frac{59}{11} } or -i*\sqrt{\frac{59}{11} }

Step-by-step explanation:

11b^2-9=-68

11b^2=-59

b^2=-59/11

b=i*\sqrt{\frac{59}{11} } or -i*\sqrt{\frac{59}{11} }

"i" in this case is an imaginary number, equal to \sqrt{-1\\}

if you haven't learned about these yet, something is wrong with the question
