If f(x) = x2and g(x) = x are two functions from R to R thenf(g(2)) isa...
Given:
- f(x) = x^2
- g(x) = x
To find:
- f(g(2))
Solution:
To find f(g(2)), we need to substitute the value of g(2) into the function f(x).
Step 1: Find g(2)
- g(x) = x
- Substituting x = 2, we get g(2) = 2
Step 2: Find f(g(2))
- f(x) = x^2
- Substituting x = g(2) = 2, we get f(g(2)) = f(2) = 2^2 = 4
Answer:
- f(g(2)) = 4
- Therefore, the correct answer is option B.
- f(x) = x^2
- g(x) = x
To find:
- f(g(2))
Solution:
To find f(g(2)), we need to substitute the value of g(2) into the function f(x).
Step 1: Find g(2)
- g(x) = x
- Substituting x = 2, we get g(2) = 2
Step 2: Find f(g(2))
- f(x) = x^2
- Substituting x = g(2) = 2, we get f(g(2)) = f(2) = 2^2 = 4
Answer:
- f(g(2)) = 4
- Therefore, the correct answer is option B.
