Scale for the horizontal axis is in increments of 1. Scale for the vertical axis in in increments of 100. Black – Lesha, Blue - Keon Part B:What does the rate of change for each line represent? The rate of change represents the amount of calories per snack.Part C:What is Lesha’s rate of change? Answers will vary.Example: 100 calories/snack. Part D:How does Lesha’s rate of change compare to Keon’s rate of change? Why are the two rates different from one another? In this case it doubles - the rates are different because with healthy snacks the <span>caloric intake per snack is less than unhealthy snacks.</span>

The function has a domain of all real numbers . True
<em>The cube root of real number is also real. The negative sign is outside he radical so it cannot result to an imaginary number.</em>
The function is a reflection of y =³√x . True
The function is always increasing. False
<em>When getting the cube root of a number the result is alway smaller. So the domain of the function should be decreasing not increasing.</em>
The function has a range of {y|– < y < } . False
The function passes through the point (3, –27) . False
<em>When this values are substituted it the function they don't satisfy it. </em>
Let the third side be x :
( 3√5 )^2 = 6^2 + x^2
45 = 36 + x^2
x^2 = 45 - 36
x^2 = 9
x = 3
