Answer:
1) 4 miles per hour
2) Yes, No
Step-by-step explanation:
Speed is the slope of the distance-tome graph.
The steepest slope is:
((5-3)/(2-1.5) = 2/0.5
= 4 miles per hour
A relationship is a function when every input has a unique output
Equation:
B = 5 × 2^t
This is a function
This is an exponential function, not a linear
