How many real solutions does f(x)=−2x^2−1 have, based on the graph? (1 point)
one real solution because the graph intersects the y-axis once one real solution because the graph intersects the y -axis once two real solutions because the graph is symmetric about the y-axis two real solutions because the graph is symmetric about the y -axis one real solution because the graph touches y-axis at y=−1 one real solution because the graph touches y -axis at y equals negative 1 no real solutions because the graphs neither touches nor crosses the x-axis
The correct answer is:
One real solution because the graph intersects the y-axis once.
