For a function to be continuous at an x-value, say -17, you need to make sure two things line up:
The limit from the left equals the limit from the right.
This limit equals the functions value.
The left hand limit involves the first piece, f(x) = 20x + 1:
The right hand limit invovles the second piece, f(x) = -10x^2:
Since the two one-sided limits don't match, the function is not continuous at x=-17.
Step-by-step explanation: B
put the center of the circle on the right of the line and the edge of the circle on the p. Make part of a circle. you dont have to do the whole circle, but you can if you want.
do the same thing again but on the other side of the line.
now it should look like the first image i included (if you didnt do the whole circle)
now take your straightedge/ruler/line maker and make it go through the intersecting points on the circles, like the second image.
Note that my images are for demonstration. They're not perfect at all, they're just to show you how to do it.
