14) Ken burns 425 calories per hour when he bikes. He bikes from 3 to 7 hours each weekend.

a) Write a rule for the total number of calories burned as a function of the number
of hours Ken bikes.

b) Identify the independent and dependent variables.

c) List the members of the domain and range.

d) How many calories will he burn if he bikes 8 hours?

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!
