Question 7 • Algebraic Reasoning

Complete the table for the following function. y is equal to 3 to the x th power x negative 3 negative 2 negative 1 0 1 2 3 y 1 third 1 3 Graph the function and describe what the graph looks like.

Answer
A
Increases from left to right
B
Increases in Quadrant III
C
Decreases in Quadrant II
D
Decreases from left to right

Explanation

For y = 3^x, the values from x = -3 to 3 are 1/27, 1/9, 1/3, 1, 3, 9, and 27. Since the base 3 is greater than 1, the function’s values rise as x increases, so its graph increases from left to right. The correct choice is “Increases from left to right.”
