Tell 2 positive and 2 negative things that come to mind about radiation/radioactivity

Hey

First, you need to know that radiation is vital for life on earth and the process of photosynthesis. also, you couldn't see without radiation.

But some radiation is harmful to DNA such as x-rays and gamma rays. and most of the energy is lost to radiation (created by heat, fission, and fusion).

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
