Flashcard- Function Operations

Front

What is function composition?

Back

Function composition is the process of applying one function to the results of another function. If you have two functions, f(x) and g(x), the composition is denoted as f(g(x)).

What does it mean if a function is undefined at a certain point?

Back

A function is undefined at a certain point if there is no output for that input, often due to division by zero or taking the square root of a negative number.

Front

Calculate h(f(-2)) if f(-2) = 10 and h(x) = x - 10.

Back

h(f(-2)) = h(10) = 10 - 10 = 0.

Front

Given f(x) = 4x - 10 and g(x) = 2, find \frac{f}{g}(x).

Back

\frac{f}{g}(x) = \frac{4x - 10}{2} = 2x - 5.

What is the output of f(g(3)) if g(3) = 2 and f(x) = 2x?

Back

f(g(3)) = f(2) = 2 * 2 = 4.

Define the term 'domain' in relation to functions.

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

Define the term 'range' in relation to functions.

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the straight-line distance from the starting point to the endpoint, considering direction.

Front

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

Back

g(2) = 2 + 1 = 3, so f(g(2)) = f(3) = 3^2 = 9.
