Which parent graph is pictured above?

• $y=\left|x\right|$

• $y=\sqrt{x}$

• $y=x$

• $y=x^2$

What is the correct first step when solving this equation?

Assume you are performing each step to both sides of the equation

• It is quadratic and is set = to 0, so try factoring.

• Add 15

• Divide by 2

• Divide by x

This shows the graphs of   $y=2$  and $y=\left|x+1\right|$ .

When is  $\left|x+1\right|\ge2$  

•  $x=-3\ and\ x=1$  

•  $\times\le-3\ and\ x\le1$  

•  $x\le1\ and\ x\ge-3$  

•  $x\le-3\ and\ x\ge1$  

There are not two values that both multiply to equal -30 but also add up to 2.

What should I try next to solve this equation?

• Pythagorean Theorem

• Factoring

• Quadratic Formula

• Slope formula
