Final answer:
Out of the given options, x³ and 2ˣ grow faster than x².
Step-by-step explanation:
Out of the given options, only A) x³ and D) 2ˣ grow faster than x².
To determine which functions grow faster, we can compare the exponents of the given functions. In this case, x³ has a larger exponent than x², and 2ˣ has an exponent that increases exponentially with x.
For example, if we substitute x = 2, we get:
x² = 2² = 4
x³ = 2³ = 8
2ˣ = 2² = 4
As we can see, x³ and 2ˣ have larger values than x² when x = 2, indicating that they grow faster.
