the answer is A ,when x=0,g(x)is-1,so when u add x into the g(x),which is given below,u can find C,D,E,g(x) is no equal to -1,when you add x=1 into g(x)(A,B),you can find g(x) of B is 0,which is no equal the answer giving above(g(x)=2),but A is all right.

I need help understanding this!

The basic idea is that multiplying by 10 just moves the decimal point one place to the right. It makes the number bigger.

4.8 x 10 = 48

4.8 x 10 x 10 = 48 x 10 = 480

Each time you multiply by another 10, the decimal point moves one more time.

The expression $10^5$ says you're going to multiply by 10 five times in a row. So that will move the decimal point 5 places to the right.

So what do you get if you move the decimal in 4.8 five places to the right?
