I believe the first question is 4 feet / 1 second and the second answer is 16 oz / 1 lb
The exponential function is given in the form

where a is the initial value and b is the multiplicative rate of change
So lets plug the first two values of the table in this function , we get
or

Now plug second

Divide equation 2 by equation 1

On simplifying we get

or

So the multiplicative rate of change of the function is

Answer:
5 is the coefficent of y if you simplify and 3 is the constant
Step-by-step explanation:
7y-2y=5y. The coefficient is the number that goes with the variable, or letter, such as y. The constant is the number that does not have any coefficients attached to it.
