A range value of the function f(x)=−2x+6 is 0. What is its domain value?

The domain is all real numbers

-inf<x<inf

Step-by-step explanation:

First, we need to understand what the problem is asking for.

The range of a function is the set of the y-coordinates of all the points of the function.

The domain of a function is the set of the x-coordinates of all the points of the function.

"A range value" means the same as "the y-coordinate of one point."

This problem is telling you that the y-coordinate of a point of function f(x) =  -2x + 6 is 0. Then it asks what its domain value is. It is asking you what is the x-coordinate of the point that has 0 as its y-coordinate.

Simply put, for function f(x) = -2x + 6, when y = 0, what is x?

f(x) = −2x + 6

-2x + 6 = -

-2x = -6

x = 3

look up a corrdinate plane and do what the thingy says and boom

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.
