For each situation decide if the DOMAIN is discrete or continuous. Explain your thinking. A. The air temperature over the course of a day

B. The cost of hot dogs at
concession stand

C. The distance traveled on a road
trip

D. The cost of parking for a certain number of hours at a parking garage

A and C are discrete, B and D are continuous

Step-by-step explanation:

A is continuous because the temperature of the air can be any possible temperature and every possible number in between.

B is discrete because the cost can only be an exact amount of money. It couldn't be 88.7 centers, for example.

C is continuous because the distance includes every possible measurement between 0 and the total number of miles.

D is the same as B.

5 x 14?

im new, sorry if this is wrong.

step-by-step explanation:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
