Logarithms and Exponential Functions: I See You, Expo! True or False

1. Which function does not have an inverse? ->y = x3
2. Which function is an exponential function? ->y = 82x
3. Why can’t y = x30 have an inverse? ->Because it isn’t an even function.
4. What is the inverse function of y = 50x3 ->y = 3x50
5. What is the inverse function of y = 4ex + 7? ->

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 = 37x
