You are going on a road trip! You drive to your best friend's house and then get on the highway.
After 2.5 hours, you had traveled a total of 135 miles.
You can average 50 miles per hour after you leave your friend's house.

Which of these equations best shows the distance you have gone since you left your house?

Ibelieve a is the correct answer because 3 is the y-intercept you can see it from the graph. so from here the answers could only be a and c. they are differently at the sign.substitute x with 1so the equation for a is 3*(1.4)^x3*(1.4)^1 = 4.2look back at the graph it is true that when x= 1 y= 4.2if you use equation from c. when x= 1 then y will be negative number which is falseso correct answer is a
