True/False : 2 Questions
1 The following function is onetoone
f(x)= x if x belongs to [1,0]
f(x)=3x+2 if x belongs to [0,1]
2 The following parametric curve represents a line segment from (0,3) to (2,0) :
and where
For (1): I think its false, if we draw the function on the interval [1,1] we will get a graph which is similar to the graph of f(x)=x (the vshape). clearly there are horizontal lines intersect the curve of f in more than one point, so its not 11 function, so the statement is false.
For (2): I do not have any idea!

Its ok for number1.
Its true
sorry, I made mistake when i draw
its onetoone
I need number 2 please.

I see you already figured out (1), but try to be careful about writing intervals like [a,b] or (a,b) or (a,b] or [a,b). The f(x) you wrote above is not a function because the first part gives f(0) = 0 and the second part gives f(0) = 2.
For (2), first check start and end points.
x(0) = 0 and y(0) = 3
and .
So we can't conclude whether it's true or false yet.
Now express y in terms of x:
This is an equation of a line, so the answer to (2) is True.

(1) agree
(2)
now calculate and ATQ.
btw ... not to cramp your style, but the pink type is difficult to read.
