If f(x) = 3x2 and g(x) = 4x2+1, what is the degree of (fog)(x)?

4

Step-by-step explanation:

To solve this problem let us first find , or find the function of f(x) in terms of g(x). All we have to do is replace x with g(x) in the function f(x):

We have to find the the degree of , which is the largest exponent on one of the polynomial's terms. Notice that has the greatest exponent of 4.

Therefore, the degree of (fog)(x) is 4.

I hope this helps! Let me know if you have any questions :)

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
