Using the graph below select all statements that are true

a. this is the graph of the greatest integer function

b. f(4.5)=5

c. this graph is one to one

f. f(0)=0

e f(1.4)=1

we will select each options and then verify it

option-A:

we know that

greatest integer function is  for all real numbers, x, the greatest integer function returns the largest integer. less than or equal to x

Here , we can see that between 0 to 1 ... then value of y=0..which is less than 1

so, this is TRUE

option-B:

f(4.5)=5

since, this is greatest integer function

so, for x=4.5 , y should be 4

so, this is FALSE

option-C:

Since, this does not satisfy horizontal line test

so, it is not one to one

so, this is FALSE

option-D:

we can see that

f(0)=0

when x=0 , y=0

we are given point at origin

so, this is TRUE

option-E:

we can see that

f(1.4)=1

Since, it is greatest integer function

So, when x=1.4 and y=1

so, this is TRUE

A. This is the graph of the greatest integer function

D. f(0)=0

and

E. f(1.4)=1

are all right.

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.
