Question

The graph above shows the nature of the function $f$ . Determine,with the help of the graph, the number of distinct real roots the function $f$ possesses.

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is D 4

As per given graph, the function the value of $y$ is $0$, four lines, because graph cut $x$ axis four times.

Then real roots of function $f$ are $4$ (four).
