How many real solutions does the function shown on the graph have?
can someone explain?
one, two, none, or can't be determined?

This is a quadratic function.y = a x² + b x + cHere the function crosses x-axis at the points: ( - 4, 0 ) and ( 0 , 0 ).The function is y = x² + 4 x.The zeroes are: x1 = - 4,  x2 = 0.Two real solutions.

Ican’t answer if there is no diagram
