22. Given g(x)=2x3x25x, with g(2)=10. Find f(10), where g1(x)=f(x).






Answer is: option1

123

Solution:

We are asked to find f(10), where g1(x)=f(x). From the inverse derivative rule:

f(y)=1g(x)wherey=g(x)

Step 1: Find g(x)

For g(x)=2x3x25x, we differentiate:

g(x)=6x22x5

Step 2: Evaluate g(x) at x=2

At x=2:

g(2)=6(2)22(2)5=6(4)+45=24+45=23

Step 3: Find f(10)

Since g(2)=10, we have:

f(10)=1g(2)=123

Final Answer:

The correct answer is: a) 123
