we are given
we can check each options
option-A:
-1,1
we can plug x=-1 and x=1 and check whethet f(x)=0
At x=-1:
At x=1:
so, this is TRUE
option-B:
0,1
we can plug x=0 and x=1 and check whethet f(x)=0
At x=0:
At x=1:
so, this is FALSE
option-C:
-2,-1
we can plug x=-2 and x=-1 and check whethet f(x)=0
At x=-2:
At x=-1:
so, this is FALSE
option-D:
-1,0
we can plug x=-1 and x=0 and check whethet f(x)=0
At x=-1:
At x=0:
so, this is FALSE
Remark
the question depends on d= r * t
d = the distance in miles.
r = the rate of travel in miles per hour
t = the time in hours.
Step One
Rearrange the formula so you are solving for the rate.
d = r * t Divide by t
4 5/6 = (4*6 + 5)/6 = 29/6
r = d / t
Step Two
Substitute into the equation.
Step Three
Turn the bottom fraction upside down. Multiply these two together.
r =
r = 29/4 miles hour.
Step Four
Solve for d when t = 1 hour.
d = ??
r = 29/4 miles / hour
t = 1 hour.
d = 29/4 * 1
d = 29/4 miles
That's as simple as you can get it unless you want 7 1/4 miles or 7.25 miles
