Given:

Given the graph of some quadratic equations

Required: Number of real solutions of each quadratic equation.

Step-by-step explanation:

The solutions of a quadratic equation are the x-values that crosses the x- axis.

So, the number of real solutions of a quadratic equation is the number of times the curve crosses the x-axis.

On the first graph, the graph cuts the x-axis at two places. Hence, it has two real solutions.

On the second graph, the graph cuts the x-axis at two places. Hence, it has two real solutions.

On the third graph, the graph cuts the x-axis at only one place. Hence, it has only one real solution.

On the fourth graph, the graph not cut the x-axis anywhere. Hence, it has no real solution.

Final Answer: First graph - Two real solution

Second graph - Two real solution

Third graph - One real solution

Fourth graph - No real solution
