Which of the following represents the quadratic function f (x) = 5(x − 2)2 − 7 in standard form?

Factorize: x^2+8x+10 i just solved it but i don't know if the process is correct

F(x)= 1/x-4, g(x)=4x+1/x a. use composition to prove whether or not the functions are inverses of each other. b. express the domain of the compositions using interval notation.

Monica build a remote control toy airplane for science project to test the plane she launched it from the top of a building the plane travel a horizontal distance of 50 feet before landing on the ground a quadratic function which models the height of the plane in feet relative to the ground at a horizontal distance of x feet from the building is shown
