The result when a number is divided by 2 is equal to the result when that same number is divided by 4. what is that number?

F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)

Can someone tell me if this is perpendicular? !

20 points 1. your friend, taylor, missed class today and needs some identifying solutions to systems. explain to taylor how to find the solution(s) of any system using its graph. 2. taylor graphs the system below on her graphing calculator and decides that f(x)=g(x) at x=0, x=1, and x=3. provide taylor some feedback that explains which part of her answer is incorrect and why it is incorrect. f(x)=2x+1 g(x)=2x^2+1
