For the piecewise Function below, which of the following statments is true? Someone please help me

Remark
Let's just figure out what f(1) and f(3) are and what equation to use.
f(1)
f(1) is defined by the top condition. Look at the condition carefully. -3 ≤ x ≤ 1
So the value of f(1) is
(x + 1)² -1
(1 + 1)² - 1
2² - 1
4 - 1 = 3
f(3)
f(3) is governed by the middle condition. 1 < x ≤ 3
The value of f(3) is - x + 2 = - 3 + 2 = - 1
Conclusion
f(1) > f(3)
Comment
Both f(1) and f(3) are defined. You just have to look around to find out where. D is wrong.
We calculated both f(1) and f(3). f(1) is larger than f(3) so that is your answer.
The first one and the third one are correct. because for the when you plug 1 on the first piece wise function you get 3. f(3) =1. and f(1)=3 so f(1)>f(3)

It is 46 if you divide 34 by 16 you get 2.125 then divide 100 by 2.125 and you get 47.05 the 0 means go down if you are rounding which brings it to 46
ΔTXV is an <span>isosceles triangle because ∡T = ∡X therefore TV = VX. 3x - 24 = 2x + 1 |subtract 2x from both sides x - 24 = 1 |add 24 to both sidesx = 25 </span>
Answer:
$4.19
Step-by-step explanation:
Usually, we use the slope formula to find the slope of a line when we know two points on the line. But if we already know the slope of a line, we can use the slope formula to find a missing coordinate of a point on the line.
