Answer:

No.

Step-by-step explanation:

As x increases 2^x will grow faster than 5 x^2. This is because the x in 2^x is an exponent and its graph grows very steeply compared with 5x^2 , as x increases.

For example when x = 10

5x^2 = 5*10^2 = 500

2^x =  2^10 =1024

When x = 11:

5x^2 = 605

2^x = 2048 and the difference will continue to increase.
