So remember that the distance formula is .
1.
Distance between (4,-5) and (4,-2) is 3 units.
2.
Distance between (1,1) and (-1,4) is √13 (or 3.61 rounded to the hundreths) units.
A cab company charges a $5 pick up fee and $1 for each mile up to 10 miles and $2 per mile for each mile over $10. Which graph c
orrectly represents the charge, y, in dollars for a cab ride of x miles?
(there’s one more graph that i couldn’t fit in the screenshot. if any of these choices are wrong,let me know. it must be the graph that i couldn’t show)

Answer:
There is no exponential function passing through (1,1) and (5,5).
Step-by-step explanation:
We have the following exponential function
The function passes through these two points:
(1,1): This means that when t = 1, y = 1
(5,5): This means that when t = 5, y = 5.
So
(1,1)
(5,5)
From above, we have that:
1 cannot be equal to 1/5, so this is wrong.
This means that there is no exponential function passing through (1,1) and (5,5).
