Write an exponential function in the form y=ab^xy=ab x
that goes through points (0, 18)(0,18) and (2, 288)(2,288).

Step-by-step explanation:

We want an exponential equation in the following format:

Point (0,18):

This means that when . So

So

Point (2,288):

This means that when . So

.

So

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
