Question

When looking at a graph of a parabola we can find the real solutions by seeing where the graph crosses the:

A. x axis
B. y axis
C. vertex
D. origin​

Answer 1

A. x-axis

Explanation:

The solutions of an equation are also thw zeroes of the equation, i.e, the x values where the function is 0

Answer 2

The x-axis

Explanation:

When the y-value is 0, x value can be anything from -∞ to ∞. So, any solution would lie on the x-axis only when y = 0.
