I need help with these questions plz

The first one is an acute triangle

The second one is a right triangle

The third one is obtuse triangle

Ok the other answer is better than mine ;-;

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
