f(x)=−(x+2)(x−2)

g(x)=2|x+2|

What is the solution to f(x)=g(x) ?

The only thing difficult here is to decide which graph is the correct one

f(x) is the same on both graphs

g(x) = 2 l x + 2 ] is the absolute value graph of l x l shifted two units to the left with a vertical stretch

The " vertex" of l x l = (0, 0)

So...the "vertex" of 2 l x + 2 l is (-2, 0)

So....the first graph is correct

And the x values for the solutions are

x = -2 and x = 0
