What are the roots of f(x) = x2 - 48? -48 and 48 -24 and 24 -8/5 and 83 -4,3 and 43

Click on the y intercept. -x +4 i know you cant click on it so could you just say the coordinates like (example - (1,0) you so much.

If f(x) and g(x) are inverse functions of each other, which of the following shows the graph of f(g(x)

Without any equipment, you can see stars that are 2{,}800{,}0002,800,0002, comma, 800, comma, 000 light-years away. by looking through a small telescope, you can see stars that are 3{,}112{,}000{,}0003,112,000,0003, comma, 112, comma, 000, comma, 000 light-years away. approximately how many times as far can you see using a small telescope as without any equipment?
