Poll

Two truths and a lie.

I've had many jobs over the years. I taught 8th grade math, I worked at Nordstrom, I worked at a pawn shop.

Which one is the lie?

• 8th grade math

• Nordstrom

• Pawn Shop

Linear Function

f(x) = 2x-3

or

y = 2x-3

Quadratic Function

y = 3x²-x-4

or

f(x) = 3x²-x- 4

Square Root Function

 $y=2\sqrt{x}$  

Absolute Value Function

 $y=\left|x-1\right|$  

Exponential Growth

g(x) = 2^x

Exponential Decay

y=0.5^x

Cube Root

 $y=^3\sqrt{x+1}$
