What is the range of the function graphed below

4223422222222222222222222222

-3<y<=3

Step-by-step explanation:

The function ranges from - 3 to 3,but 3 is included

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope

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
