Write the equation of the parabola in vertex form.

y = (x+3)² - 4

y = (x - a)² + b

where (a,b) is the upper/lower point of the curve

If you still dont understand, look at pic for more example.

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
