Comparing Parent Functions

I know the function is a linear function when I see....

• the exponent 2 / a degree of 2

• the "bars"

• X with no exponent higher than 1 / a degree of 1

• I just hope for the best

I know the function is a quadratic function when I see....

• the exponent 2 / a degree of 2

• the "bars"

• X with no exponent higher than 1 / a degree of 1

• I just hope for the best

I know the function is an absolute value function when I see....

• the exponent 2 / a degree of 2

• the "bars"

• X with no exponent higher than 1 / a degree of 1

• I just hope for the best
