The values in the table represent a function. A 2-column table with 5 rows. The first column is labeled x with entries negative 6, 7, 4, 3, negative 5. The second column is labeled f of x with entries 8, 3, negative 5, negative 2, 12. Use the drop-down menus to complete the statements. The ordered pair given in the first row of the table can be written using function notation as . f(3) is . f(x) = –5 when x is .

The ordered pair in the row you described would be (6,8), since we write ordered pairs in the form (x,y) and those are the x and y values in the table.

f(3) is asking "What y-value is paired with the x-value of 3?"  

f(x) = -5 is asking "What x-value is paired with the y-value of -5?"

Can you read the answers for the last two from your table?

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.
