Use the following graph below , select all statements that are true and you

we will select each options and then we verify it

(a)

since, this is greatest integer function

so, it's value will be equal to lesser integer value

so,

so, this is FALSE

(b)

since, this is greatest integer function

so, it's value will be equal to lesser integer value

so,

so, this is TRUE

(C)

This is FALSE

(D)

This is TRUE

(E)

Since, it does not satisfy horizontal line test

so, it is not one to one

so, this is FALSE

answer: 12

step-by-step explanation:

because yes

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
