Question

What does plotting sufficient solution points mean?

What is a solution point?

Answer 1

As a blind guess, I think "solution points" here refers to points that are on the function.

Explanation:

Given that this question has been categorized "Graphing Quadratic Functions," I imagine that you are graphing a quadratic function. To graph a function, you'll want to know some points that it passes through. An `(x,y)` pair that makes the equation true solves the equation.

You need to plot "sufficient solution points" because you want to be able to draw your curve through the points to accurately represent the quadratic. Points such as the vertex `(-b/(2a),f(-b/(2a)))`, any intercepts (`(0,y)` or `(x,0)`) are very useful points for drawing a curve.

"Plotting a point" simply means to draw it on the coordinate plane. You can then draw your curve through the points.
