How many real solutions are there for the function graphed below?

no real solution
1 real solution
2 real solutions
infinite number of solutions

1.
A graph is formed by plotting all pairs (x,y), such that y is f(x), for a certain function f.

for example:

Take a look at the graph. (x, y)=(3, 5) is on the graph. This means that f(3)=5      (because f(x)=y)

2.
The real solutions of a function f, are those points x, such that f(x)=0.

in the graph we see no point (x, 0), so there are no real solutions.

 No Real Solution

There is no graph to go along with this
