Given: f(x) = x + 2

[f(x)] 2 =

x^2+4x+4

Step-by-step explanation:

its basically (x+2) * 2

you can do this several different ways but the easiest is the box method

basically, draw a 2x2 table. on the outside of the boxes, put x and +2, two times.

x*x= x^2

x*2= 2x

2*x=2x

2*2=4

then combine your answers:

x^2 +2x+2x +4

since there is two 2x's, we can combine those. so. 2x+2x=4x.

x^2+4x+4

or u could go to www.symbolab.com and type in the problem, and it will show you step by step to solving this problem. the REAL way. this is how i did it when i got stuck.

x^2+4x+4

Step-by-step explanation:

if x decreases by 4 then y increases by 10
