Question

Use the graph of logarithmic function f(x)
to answer the question.

A graph of an increasing log function that passes through (1, 0) and has a vertical asymptote at x equals 0.


What is the domain and range of the function?

Match the domain and range with the corresponding set of points.

Domain
Range
Options: (-∞,0) (0,∞) (-∞,∞) (1,∞) (0,1) (-∞,1)

Answer 1

Graph the function and identify the domain and range.

y equals negative 3 x squared
A. A coordinate plane with a parabola graphed. The parabola opens up with vertex at (0, 0). Domain is negative infinity to infinity; Range is 0 to infinity.

domain: (–∞, ∞)
range: [0, ∞)
B. A coordinate plane with a parabola graphed. The parabola opens down with vertex at (0, 0). Domain is negative infinity to infinity; Range is negative infinity 0.

domain: (–∞, ∞)
range: (–∞, 0]
C. A coordinate plane with a parabola graphed. The parabola opens down with vertex at (1, 0). Domain is negative infinity to infinity; Range is negative infinity 0.

domain: (–∞, ∞)
range: (–∞, 0]
D. A coordinate plane with a parabola graphed. The parabola opens down with vertex at (negative 1, 0). Domain is negative infinity to infinity; Range is 0 to infinity.

domain: (–∞, ∞)
range: [0, ∞)

Answer 2

Domain: (-∞,0)
Range: (1,∞)

Answer 3

B. A coordinate plane with a parabola graphed. The parabola opens down with vertex at (0, 0). Domain is negative infinity to infinity; Range is negative infinity 0.

domain: (–∞, ∞)
range: (–∞, 0]
