1. 
Which function does not have an inverse? > y = x^{3}

2. 
Which function is an exponential function? > y = 8^{2}x

3. 
Why can’t y = x^{3} have an inverse? > Because it isn’t an even function.

4. 
What is the inverse function of y = 50x^{3} > y = 3x^{50}

7. 
If the population of a city grows at the same rate every year, what kind of function would best model its growth? > Radical function

8. 
If a plane climbs quickly at first and then slows its ascent over time, what kind of function would best model its growth? > Quadratic function

9. 
Can a linear function ever be greater than an exponential function? > Sometimes, depending on the base, coefficients, and other terms of each equation.

10. 
Which function is a logarithmic function? > y = 3^{7x}
