The solutions are the values of x where the curve crosses the x-axis. Can you read the graph?

Look at the graph. Trace along the curve and find the spots where it crosses the x-axis, which is the line y=0. At each such spot, make note of the value of x. Those x values are the solutions.

If the curve never crosses the x-axis, then choice (d) would be correct.

I got B as my answer!

Look at the curve again...does it only cross once?

the wording is a bit deceptive, implying there is only one solution...but you know better, right? :-)

Is this the exact question What is the solution to the quadratic equation graphed below? That does not make a lot of sense. But often, people want to know where the quadratic equation is equal to zero, in other words, what are its "roots" See attached.

No, that's commonplace usage in most texts I've seen...

if you are talking about a x^2 + bx +c =0 then yes. However, for y= a x^2 + bx +c you must specify a specify y value to solve for x. The min or max is an equally interesting point to solve for.

So then our answer would be A?

They want to know where the parabola crosses the x-axis. It crosses in 2 places. See attachment in the previous post.

When speaking of solutions to a polynomial, it is customary to take y = 0.
