Answer:
d. The function is negative for all real values of x where x<-3 or x>-1.
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Please have a look at the attached photos.
My answer:
Given the Quadratic function as following:
f(x) = –(x + 3)(x – 1)
As we can see, the graph of the function is a downward parabola because the parameter a = -1 is negative.
It's root are -3 and 1.
Let analyse 4 answers:
Wrong, The function is positive where -3 < x < -1
wrong, where where x> -1. the function is negative
Wrong. The function is negative for all real values of x where x > 0.
True, as it can be seen in the photo.
Hope it will find you well.
Answer:
The answer is 1122.
Step-by-step explanation:
First, multiply 34 by 3. That gives you 102.
Then multiply 34 by 3 again. But when you're writing this down in calculations, put a zero in the ones column then write your answer. (I'll show an example of what this looks like at the bottom.
Then, add your answers and you'll have your answer...

namely, let's rationalize the denominator in the fraction, for which case we'll be using the <u>conjugate</u> of that denominator, so we'll multiply top and bottom by its <u>conjugate</u>.
so the denominator is 5 + i, simply enough, its conjugate is just 5 - i, recall that same/same = 1, thus (5-i)/(5-i) = 1, and any expression multiplied by 1 is just itself, so we're not really changing the fraction per se.
