F(x) = x2 + 2x – 15. What are the x-intercepts of the function?

X-intercepts at x = -5 and x = 3

Step-by-step explanation:

To solve this, you first need to know that x-intercepts occurs at the "zeros" of the function. In other words, the x-values you get when you make y (aka f(x)) equal 0. If you don't like to look at the function and do logical factoring, you can always rely on the quadratic formula too; it will never lead you wrong. For me I just did logical factoring in my head and got (x+5)(x-3). The last step, because remember this is set equal to zero, is to get the x-values x = -5 and x = 3. Hope this helps!

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.

the answer to your question is b.
