Please help math thank you very much​

He mass of a single atom of carbon can be found by dividing the atomic mass (12.01 g) by 6.022 x 10^23. which is the mass of a single carbon atom, correctly written in scientific notation with the correct number of significant figures?

The functions f(x) and g(x) are shown in the graph f(x)=x^2 what is g(x) ?

What is a correct first step in solving the inequality-4(3-5x)> -6x+9
