Question

On a coordinate plane, a line with a 90-degree angle crosses the x-axis at (negative 4, 0), turns at (negative 1, 3), crosses the y-axis at (0, 2) and the x-axis at (2, 0).

What is the range of the function on the graph?

all real numbers
all real numbers less than or equal to –1
all real numbers less than or equal to 3
all real numbers less than or equal to 0

Answer 1

C

Explanation:

took the test

Answer 2

The third option is the required number.

Explanation:

As shown in the given image, the value of x can be all the real numbers. The maximum value of y is 3.

But whatever the value of x is, the value of y can not be greater than .

Hence, the value of y will be either 3 or less than 3.

Thus the range of the function is all real numbers less than or equal to 3.
