What is the graph function f(x) = x^3 +9x^2 +2x -48?

y=9x^2+2x-48

Step-by-step explanation:

a. Discrete

b. Continuous

c. Continuous

d. Discrete

e. Discrete

f. Continuous

Step-by-step explanation:

The difference between discrete variable and continuous variable is that discrete variable can take a value in the form of whole numbers while continuous variable can take any form of value whole numbers or a fractions.

In other words when the values of variable can be counted then it is a discrete variable and when the values of variable can be measured then it is a continuous variable .

a.

Variable X consists of number of automobile accidents which can be counted. So, it is a discrete variable.

b.

Variable Y consists of length of time which can't  be counted but can be measured. So, it is a continuous variable.

c.

Variable M consists of amount of milk produced which can't  be counted but can be measured. So, it is a continuous variable.

d.

Variable N consists of number of eggs laid which can be counted. So, it is a discrete variable.

e.

Variable P consists of number of buildings permit issued which can be counted. So, it is a discrete variable.

f.

Variable Q consists of weight of grain which can't  be counted but can be measured. So, it is a continuous variable.
