Composition of functions is the operation where one function is applied to the result of another function, denoted as (f ∘ g)(x) = f(g(x)).

3.

FLASHCARD QUESTION

Front

If f(x) = x^2 and g(x) = x + 1, what is (f + g)(x)?

Back

(f + g)(x) = x^2 + (x + 1) = x^2 + x + 1.

4.

FLASHCARD QUESTION

Front

Calculate (f - g)(x) if f(x) = 2x + 3 and g(x) = x - 1.

Back

(f - g)(x) = (2x + 3) - (x - 1) = x + 4.

5.

FLASHCARD QUESTION

Front

What is the formula for (f * g)(x)?

Back

(f * g)(x) = f(x) * g(x), which means multiplying the outputs of f and g for the same input x.

6.

FLASHCARD QUESTION

Front

If f(x) = 3x and g(x) = 2x^2, find (f / g)(x).

Back

(f / g)(x) = 3x / (2x^2) = 3 / (2x) for x ≠ 0.

7.

FLASHCARD QUESTION

Front

Find f(g(2)) if f(x) = x^2 and g(x) = 3x + 1.

Back

g(2) = 3(2) + 1 = 7; then f(g(2)) = f(7) = 7^2 = 49.
