Domain = All real numbers

Range = y ≥ 0

Step-by-step explanation:

As for the domain... you can substitute any value for x and get a mathematical response. Therefore... the domain is all real numbers

Because we are finding the absolute value of the entire function... we know that the final answer cannot be negative. (Don't forget that it can still be 0) Since y can only be positive... we define the Range as y ≥ 0

c

step-by-step explanation:

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.
