• Every time the quadratic function grows, it will grow by a smaller rate

• The exponential function will always grow by a factor of 4

• The exponential function will not overtake the quadratic one

• Every time the quadratic function grows, it will grow by a faster rate

Tyler concludes that 5x^2 will always take larger values than 2^x for the same value of x. Do you agree? Explain or show your reasoning.

What is the difference between a quadratic function and an exponential function in terms of reaching 0?

• An exponential function can never equal 0, while a quadratic function can equal 0.

• Both quadratic and exponential functions can never equal 0.

• Both quadratic and exponential functions can equal 0.

• A quadratic function can never equal 0, while an exponential function can equal 0.

As x approaches positive infinity, my function’s values will eventually exceed the other function’s values.
