The third choice is correct and can be found by plugging the values into Point-Slope Form.
In a right-triangle, if either of the other two angles are "half that measure", or half of 90°, that means 45°, then the last angle will also have to be a 45° one too, and the sides coming from the 90° angle, will be equal twins, and therefore they can only make up one type-length hypotenuse, and due to that, you can only make that one triangle. Check picture below.
Answer: 6.5%
Step-by-step explanation:
Interest = Amount repaid - Amount borrowed
= 226 - 200
Interest = 26
Si = ( prt) / 100
26 = (200 x r x 2) / 100
26 = 4r
r = 6.5%
Each piece of this function is continuous on its respective domain (because all polynomials are continuous functions), meaning
• 2 - x exists for all x < -1
• x exists for all -1 ≤ x < 1
• (x - 1)² exists for all x ≥ 1
So this really just leaves the points where the pieces are split up, i.e. x = -1 and x = 1. At both of these points, the two-sided limit exists as long as the one-side limits from both sides exist and are equal to one another.
At x = -1, as I said in my comment, you have

while

But -1 ≠ 3, so the two-sided limit

does not exist. So a = -1 is one of the points you would list.
At x = 1, we have

while

and again the one-sided limits don't match, so this two-sided limit also does not exist, making a = 1 the other answer.
