The graph does not touch the x axis anywhere. That means there are no points on the graph that have a y value of 0 . There are no x values that cause y to be zero.
So... there are no real solutions to this equation: f(x) = 0
Hectictar is correct of course but the question is very badly worded becasue this is the equaton of
Which has an infinite number of solution pairs.
\(0=(x-2)^2+6\) has no solutions
