Which relation is a function?
If $f(x) = 2x^2 - 3x$, what is $f(-2)$?
The domain of $f(x) = \sqrt{x - 4}$ is:
The range of $f(x) = (x - 2)^2 + 5$ is:
For $f(x) = |x - 3|$, which statement is true?
If $f(x) = x^2$ and $g(x) = x + 1$, then $f(g(x))$ equals:
If $f(x) = 3x - 7$, then $f^{-1}(x)$ is:
Which function is even?
Which function is odd?
A function has an inverse function only if it is:
To make $f(x) = x^2$ have an inverse function, a valid domain restriction is:
The graph of $y = f(x) + 4$ is the graph of $y = f(x)$ shifted:
The graph of $y = f(x - 2)$ is the graph of $y = f(x)$ shifted:
If $f(x) = 1/(x - 3)$, which value is excluded from the domain?
If $f(x) = 2x + 1$ and $g(x) = x^2$, then $g(f(2))$ equals:
