Me with both question 18 and question 19.

A & A

Step-by-step explanation:

18)the graph of the function is stretched by half, thus it compresses toward the x axis. while the +4 in the root is moved 4 to left.

19) set equations equal to each other and solve for x and y one at a time

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
