Front

Which parent function does NOT have an x-intercept?

Back

Exponential function

Front

Find the vertical asymptote(s) of the function: 3x / (x^2 - 9)

Back

x = 3, x = -3

Front

Which of these is NOT an asymptote on this graph? x = -3, x = 3, y = 2, y = -3

Back

y = -3

Front

Find the horizontal asymptote of the function: 3x / (x^2 - 9)

Back

y = 1/2

Front

Define vertical asymptote.

Back

A vertical asymptote is a line x = a where a function approaches infinity or negative infinity.

Front

Define horizontal asymptote.

Back

A horizontal asymptote is a line y = b that a function approaches as x approaches infinity or negative infinity.

Front

What is the parent function of a quadratic equation?

Back

f(x) = x^2

Front

What is the parent function of an exponential equation?

Back

f(x) = a^x, where a > 0 and a ≠ 1.

Front

What is the general form of a rational function?

Back

f(x) = P(x) / Q(x), where P and Q are polynomials.
