WebMar 13, 2016 · Consider first y = x. This means that whatever value you give to x ands up being the value of y. x is positive so as you move from left to right the graph line goes upwards. Consequently for every 1 along the line has gone up 1 as well. Now think about the +2. This has the effect of lifting the graph up by the value of 2. Build a table of values.

So now we know that it will change the sign (negative) when x < −2. It's best to treat a function with an absolute value as two functions. x > − 2 ⇒ y = x +2 +3 ⇔ y = x + 5. x < − 2 ⇒ y = − (x + 2) +3 ⇔ y ... how to spades
