Question

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

you didn't attach figure which is necessary to solve your question. I attached. may be it will help you.


see graph,
it seems like modulus function, well we have to find just range of function. you know range of function f(x) is defined for all real value of x.
e.g., all value of y where graph is appeared is known as Range.

here you can see that, graph doesn't exist after y = 3. hence, range must be ≤ 3

hence, option (3) is correct .
all real numbers less than or equal to 3.
