Which graph represents a function? On a coordinate plane, a straight vertical line crosses the y-axis 0 times and the x-axis 1 time. On a coordinate plane, a curved line crosses the y-axis 2 times and the x-axis 1 time. On a coordinate plane, 2 curved lines are shown. Both lines touch the y-axis 1 time and the x-axis 1 time. On a coordinate plane, a straight horizontal line crosses the y-axis 1 time and the x-axis 0 times.

i dont know

step-by-step explanation:

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

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
