Answer:
B
Step-by-step explanation
a function has to be on a graph and pass the horizontal line test. if it does not pass it then it will not be a function
The answer would be line segment.
Hey there!☺
(-∞, 5)
You need to convert the inequality as an interval notation.
as interval notation would be written like this:
(-∞, 5)
Hope this helps!
Step-by-step explanation:
Inflection points are where a function changes concavity (the second derivative changes signs). At x = 4, f"(x) goes from negative to positive, so that's an inflection point. However, at x = 8, we don't know if f"(x) changes signs or not. So we can't say that that's an inflection point.
To solve those you need to FOIL or rainbow the distributive property
hope this helped
