MULTIPLE CHOICE:
What is the domain of the function represented by this graph?
the graph of a quadratic function y = x^2 – 4 with a minimum value at the point (0,-4)

A. x ≤ 0
B. all real numbers
C. x ≥ 4
D. -2 ≤ x ≤ 2

this is not the answer this is just a question. is this middle school math?

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.

answer:

a=9
